Vitamin A for Skin: Benefits, Risks, and Limitations

Beta-carotene-containing serums can help protect the skin from free radicals and promote a more radiant complexion. Incorporate a Beta-Carotene Mask : Incorporate a beta-carotene-rich mask into your weekly skincare routine. Masks can give your skin an extra boost of antioxidants and hydration.

Eat Beta-Carotene-Rich Foods : In addition to topical applications, eating beta-carotene-rich foods can help your skin from the inside out. Include carrots, sweet potatoes, pumpkin, mangoes, and leafy greens in your diet. These foods not only provide beta-carotene but also offer a range of other beneficial nutrients for skin health.

Consider Supplements : If you have a vitamin A deficiency or find it difficult to consume enough beta-carotene-rich foods, consult your doctor about beta-carotene supplements.

However, it's essential to follow their advice and recommended dosage, as excessive vitamin A intake can have adverse effects.

Perform a Patch Test : A patch test is required before incorporating any new skincare product into your routine, including beta-carotene-containing products. Apply a small amount of the product to a small area of your skin such as the inner wrist and wait at least 24 hours for any adverse reactions, such as redness or irritation.

Combine with Other Antioxidants : Combine beta-carotene with other antioxidants such as vitamin C and vitamin E. These antioxidants work together to boost each other's ability to protect the skin from free radicals.

Topical beta-carotene treatment can help promote skin health and address specific skin issues. Because beta-carotene is a potent antioxidant and a precursor to vitamin A, it is useful in skincare. Here's how to utilize topical beta-carotene and what it can do for you:.

Antioxidant Protection : When applied topically, beta-carotene acts as an antioxidant, helping to neutralize free radicals in the skin. This shields the skin from oxidative stress caused by environmental aggressors such as UV radiation, pollution, and other pollutants.

Anti-Aging : As an antioxidant, beta-carotene can help reduce the signs of aging by combating free radicals that contribute to premature aging, such as wrinkles, fine lines, and loss of skin elasticity. Skin Rejuvenation : Beta-carotene promotes skin cell turnover, which can result in a more youthful and radiant complexion.

It aids in the removal of dead skin cells and the growth of new, healthy cells. UV Protection : Although not a replacement for sunscreen, topical beta-carotene may provide additional protection against the harmful effects of UV radiation when combined with other antioxidants.

Soothing and Calming : Because beta-carotene has anti-inflammatory properties, it can be used to soothe and calm irritated or inflamed skin. It may be beneficial to those who have sensitive or acne-prone skin.

Brightening and Even-Toning : By reducing hyperpigmentation and dark spots, beta-carotene can help to achieve a brighter and more even skin tone.

Hydration : Some beta-carotene-containing topical formulations may have moisturizing properties that help keep the skin hydrated and nourished. Beta-carotene is a naturally occurring molecule that can be found in a variety of fruits and vegetables.

Incorporating these foods into your diet can provide you with a sufficient amount of beta-carotene. Carrots, sweet potatoes, pumpkins, mangoes, apricots, spinach, kale, butternut squash, red bell peppers, melons, papayas, broccoli, tomatoes, collard greens, and peas are all high in beta-carotene.

Keep in mind that cooking can reduce the beta-carotene content of some foods. Consider steaming or lightly heating veggies instead of boiling them for long periods of time to maintain their nutritional content.

Incorporating a range of these beta-carotene-rich foods into your diet can bring a multitude of health benefits, including improved skin health, antioxidant protection, and general well-being.

While beta-carotene in food is generally safe and well-tolerated, high-dose beta-carotene supplements may have potential side effects and safety concerns. Here are some things to keep in mind when taking beta-carotene supplements:.

Carotenosis Skin Discoloration : Excessive beta-carotene intake, typically through supplements, can cause carotenosis, a harmless condition. This condition causes the skin to turn yellow or orange, especially in areas with thicker skin, such as the palms and soles.

It can also affect other parts of the body, including the face. Carotenosis is usually reversible if the amount of beta-carotene consumed is reduced. Medications : High-dose beta-carotene supplements may interact with some medications.

For example, beta-carotene supplements may interfere with the absorption of certain fat-soluble drugs, such as cholesterol-lowering medications and some anti-inflammatory drugs. Increased Lung Cancer Risk in Smokers : Some studies have suggested that high-dose beta-carotene supplementation may increase the risk of lung cancer in smokers or people exposed to asbestos.

As a result, beta-carotene supplements are not recommended for smokers or people who have smoked in the past. Pregnancy and Breastfeeding : Pregnant and breastfeeding women should avoid taking high-dose beta-carotene supplements unless their healthcare provider specifically recommends it.

Excessive vitamin A intake, including beta-carotene, has been linked to foetal harm. Allergies : Some people are allergic to beta-carotene or other carotenoids. If you notice any signs of an allergic reaction, such as itching, swelling, or difficulty breathing, discontinue use of the product immediately and seek medical attention.

Gastrointestinal Disturbances : High doses of beta-carotene supplements may cause nausea, diarrhea, and stomach cramps in some people. To reduce the possibility of side effects and ensure safe use:. Stick to beta-carotene obtained from natural food sources rather than supplements.

If you want to take beta-carotene supplements, talk to your doctor first, especially if you have any pre-existing health conditions or are taking medications. Follow your healthcare provider's or the product's dosage recommendations. Avoid high-dose supplements because a well-balanced diet usually provides enough beta-carotene for most people.

It is critical to prioritise a nutritious diet rich in nutrients, such as beta-carotene-rich fruits and vegetables. Dietary beta-carotene is generally safe and provides several health advantages without the risk of overconsumption or unfavorable side effects.

Before beginning any new supplement regimen, always visit a healthcare expert, especially if you have specific health concerns or illnesses. Excessive beta-carotene consumption, particularly through high-dose supplements, may pose hazards and have negative effects. It should be noted that these hazards are mostly related to supplementing with isolated beta-carotene rather than eating beta-carotene from natural dietary sources.

Excess beta-carotene consumption may cause skin discoloration carotenosis , medication interactions, an increased risk of lung cancer in smokers, harm to pregnant women, and gastrointestinal disturbances. To reduce the risks of excessive beta-carotene consumption:.

Beta-carotene is primarily obtained from natural food sources such as fruits and vegetables. If you choose to take beta-carotene supplements, make sure to follow your healthcare provider's or the product's instructions. High-dose supplements should be avoided unless specifically prescribed or recommended by a healthcare professional.

If you have any pre-existing health conditions or are taking medications, talk to your doctor before beginning any new supplement regimen. Remember that a well-balanced diet rich in colorful fruits and vegetables can provide enough beta-carotene for most people without the risks of excessive supplementation.

Prioritise a healthy and varied diet to promote overall health and well-being. To ensure proper and safe use of beta-carotene, whether from dietary sources or supplements, it is critical to follow safety guidelines.

Here are some precautions to take when using beta-carotene:. Obtain Beta-Carotene from Food Sources : Natural food sources are the safest way to incorporate beta-carotene into your diet. Consume beta-carotene-rich fruits and vegetables such as carrots, sweet potatoes, pumpkin, mangoes, spinach, and kale.

Excessive Supplement Use : High-dose beta-carotene supplements should be used with caution and only under the supervision of a healthcare professional. Excessive intake of isolated beta-carotene supplements can lead to potential side effects, including skin discoloration carotenosis and interactions with medications.

Consult a Healthcare Professional : Before beginning any new supplement regimen, including beta-carotene supplements, take an online dermatologist consultation , particularly if you have pre-existing health conditions or are taking medications. Consider Your Individual Needs : The recommended daily intake of beta-carotene varies depending on age, gender, and individual health conditions.

Your healthcare provider can advise you on the best dosage for you. Avoid High Doses During Pregnancy : Pregnant women should avoid high-dose beta-carotene supplements because too much vitamin A can harm the developing foetus.

Monitor for Allergic Reactions : If you notice any signs of an allergic reaction after using beta-carotene-containing products, such as itching, swelling, or difficulty breathing, stop using them immediately and seek medical attention.

Combine with Other Antioxidants : Beta-carotene collaborates with other antioxidants such as vitamin C and vitamin E. Consider including a variety of antioxidant-rich foods and skincare products to maximize your benefits.

Patch Test New Skincare Products : Before applying beta-carotene-containing skincare products to your entire face for the first time, perform a patch test on a small area of skin to check for any adverse reactions.

Prioritise a Balanced Diet : For most people, getting beta-carotene from a balanced diet is both safe and sufficient. Eat a variety of nutrient-rich foods, including colorful fruits and vegetables, to promote overall health and well-being.

Avoid Smoking and High-Risk Populations : High-dose beta-carotene supplements are not recommended for smokers or people at high risk of lung cancer, as studies have shown an increased risk of lung cancer in these groups.

By following these precautions, you can enjoy the benefits of beta-carotene while also supporting your skin and overall health. Always seek personalized advice and recommendations from a healthcare professional when in doubt or if you have specific health concerns.

Because of its multiple skin health benefits, beta-carotene is a natural key to getting a bright complexion. Beta-carotene, as a provitamin A molecule and a potent antioxidant, is essential for enhancing skin brightness and overall well-being.

Here's how beta-carotene helps you look your best:. Antioxidant Protection : Beta-carotene neutralises free radicals, which are unstable molecules that can damage skin cells and contribute to premature aging.

By reducing oxidative stress, beta-carotene helps keep the skin looking youthful and radiant. UV Protection : Beta-carotene and other antioxidants can provide an additional defence against the damaging effects of UV radiation, though they cannot replace sunscreen.

It contributes to skin health and lowers the risk of sun-induced skin damage by battling free radicals produced by sun exposure. Skin Cell Turnover : Beta-carotene encourages skin cell turnover, which is necessary for preserving a young, radiant complexion. The skin appears more youthful as new, healthy skin cells emerge from beneath the surface as older skin cells are shed.

Even Skin Tone : Beta-carotene can help to reduce hyperpigmentation and even out skin tone, resulting in a complexion that is more uniform. Soothing and Calming : Beta-carotene's anti-inflammatory properties can soothe and calm irritated or sensitive skin, promoting a healthier and calmer complexion.

Skin Rejuvenation : Beta-carotene contributes to skin rejuvenation by promoting collagen production and supporting skin renewal, reducing the appearance of fine lines and wrinkles. Hydration and Moisturization : Some beta-carotene-containing topical products may have moisturizing properties, which help to keep the skin hydrated and supple.

Brightening Effect : Beta-carotene can give the skin a natural glow, making it appear brighter and more vibrant. Consider the following to reap the benefits of beta-carotene's effects on skin health and complexion:.

Consume beta-carotene-rich foods such as carrots, sweet potatoes, mangoes, and leafy greens. To provide topical support for your skin, use beta-carotene-containing skincare products or plant extracts rich in this nutrient.

Combine beta-carotene with other antioxidants and nourishing skincare ingredients for maximum benefit. Use broad-spectrum sunscreen on a daily basis, seek shade during peak sun hours, and wear protective clothing. Remember that achieving a radiant complexion is not solely dependent on one nutrient or skincare product.

A comprehensive skincare regimen that includes a healthy diet, adequate hydration, sun protection, and a consistent skincare routine contributes to a glowing and healthy complexion.

An attractiveness score for each face pair was calculated as the percentage of times the post-supplementation face was chosen as the more attractive face. A perceived health score for each face pair was calculated as the percentage of times the post-supplementation face was chosen as the more healthy looking face.

However, several previous studies have investigated skin color preferences using online samples Lefevre et al. Both samples showed a preference for high carotenoid skin color, with no difference in the preference between the two.

This finding suggests that any additional noise due to uncalibrated monitors is relatively small compared to the color variation among the faces.

Markers of DNA oxidation 8-OHdG and lipid peroxidation isoprostane were analyzed in duplicates using competitive enzyme-linked immunoassay ELISA kits from Northwest Life Science Specialties Vancouver, VA.

A significant proportion of urinary isoprostane is conjugated to glucoronic acid, which is not assayable Yan et al. To obtain a more accurate measure of overall isoprostane level, µL of each sample was incubated with 5 µL of beta-glucoronidase for 2 h at 37°C to cleave and free the isoprostanes from their conjugated forms before running the isoprostane assays.

Creatinine was determined in duplicates using colorimetric assay kits from Northwest Life Science Specialties Vancouver. Salivary bacteria killing capacity against Escherichia coli ATCC no. Salivary supernatant was incubated with E.

coli for 30 min to facilitate bacteria killing, and then incubated overnight on trypticase soy agar TSA plates to quantify the amount of bacteria remaining see Supplementary Material for details. Images of the plates were taken together with a ruler as a size reference. We used the program ImageJ to measure the following: total number of colonies in each plate, average area of each colony, and total area of the colonies combined.

Bacteria killing capacity was calculated as the percentage difference in colony number relative to positive controls. Bacteria growth suppression capacity was calculated as the percentage difference in average colony area relative to positive controls.

Overall salivary immunity was calculated as the percentage difference in total colony area relative to positive controls. A lysoplate assay was used to determine salivary lysozyme activity. Micrococcus lysodeikticus ATCC no. Ten microlitres of whole saliva from each sample were added to 80μL of M.

lysodeikticus in duplicates in a well plate. Positive controls containing 10 μL of PBS and 80 μL of M. lysodeikticus were also added to the plate in duplicates.

The plate was incubated at 33°C for 10 min and the absorbance was measured using an M5 SpectraMax microplate reader Molecular Devices, Sunnyvale, CA. Salivary lysozyme activity was calculated as the difference in absorbance between the sample wells and the positive controls.

The semen samples were analyzed in 6 replicates immediately upon delivery using the Hamilton-Thorne CEROS Computer Assisted Semen Analysis CASA system Simmons et al. The system measures total sperm concentration, percentage motile sperm and 7 motility related variables.

Seven samples had to be diluted because they were too concentrated for the CASA to analyze see Supplementary Material for details. A portion of the post-supplementation semen sample was stored in accordance with McEvoy et al. The semen DNA fragmentation level of each sample is measured by the percentage of fragmented sperm cells see supplementary material for details.

Principal components analysis PCA was used to summarize the inter-related semen quality data and immune function data. PC1 was weighted most strongly by bacterial killing and suppression capacity.

PC2 was weighted most strongly by lysozyme activity and overall bacteria immunity. PC1 was weighted most strongly by variables related to rapid progressive motility. PC2 was weighted most strongly by variables related to the linearity of the sperm movement. PC3 was weighted most strongly by high sperm concentration and percentage motile sperm with low levels of left-right head movement.

PC3 was found to be influenced by variation in the collection procedure and abnormalities in the sample WHO see Supplementary Material for details. Therefore, we ran all analyses for PC3 on the residuals after accounting for these variables.

Difference scores were calculated for each of the 3 skin color variables yellowness, redness, and lightness , the 2 oxidative stress measures 8-OHdG and isoprostane , the 2 immune function PCs, and the 3 semen quality PCs, by subtracting the pre-supplementation scores from the post-supplementation scores.

The descriptive statistics for the dependent variables, including all the difference scores, 2-alternative forced-choice attractiveness scores, 2-alternative forced-choice perceived health scores, and post-supplementation sperm DNA fragmentation levels are presented in Table 1.

Positive values indicate an increase in a particular measure post-supplementation. During data analysis, the treatment conditions were binary coded to prevent any experimenter biases and the code was broken only after the statistical analyses were finalized.

All variables are presented as pre—post difference scores indicated by Δ with the exception of the 2-alternative forced-choice attractiveness and perceived health scores, which were scored based on the percentage of times the post-supplementation face of a participant was chosen as more attractive or healthy looking, respectively, and the sperm DNA fragmentation levels, which was measured post-supplementation.

One-way Anovas with Treatment beta-carotene, placebo as the between-participants factor were conducted for all the dependent variables, including each of the skin color difference scores yellowness, redness, and lightness , the 2-alternative forced-choice attractiveness score, the 2-alternative forced-choice perceived health score, each of the oxidative stress difference scores, each of the immune function PC difference scores, each of the semen quality PC difference scores and the post-supplementation sperm DNA fragmentation levels.

All residuals were normally distributed. These results indicate that the Treatment effect was due to an increase in yellowness in the beta-carotene group. These results show that, as predicted, beta-carotene supplementation significantly increased face yellowness and redness but not lightness.

Examples of the color variation between pre- and post-supplementation for the beta-carotene and placebo groups are shown in Figure 2. Boxplots of pre-post changes in skin yellowness, redness, and lightness by Treatment beta-carotene vs placebo. Examples of color variation between pre- and post-supplementation by Treatment condition.

Thus beta-carotene supplementation significantly enhanced facial attractiveness. Boxplots of 2-alternative-forced-choice scores for attractiveness and perceived health by Treatment beta-carotene vs placebo.

Thus beta-carotene supplementation significantly enhanced perceived health. We provide experimental evidence that the carotenoid beta-carotene enhances skin yellowness and redness and increases facial attractiveness in human males. Contrary to the carotenoid trade-off hypothesis, we did not find any effect of beta-carotene on measures of oxidative stress, immune function, semen quality, or sperm DNA fragmentation.

Thus, despite the effects of beta-carotene on facial appearance, we find no evidence that carotenoid-related skin color is an honest signal of health in human males.

Carotenoid-based coloration has been shown to influence mate choice in taxa such as birds, fishes, and lizards Endler ; Kodric-Brown ; Olson and Owens ; Møller et al. Our results suggest that carotenoid-based coloration also serves mate choice functions in humans.

First, using a randomized, double-blind, placebo-controlled experimental design, we provide strong experimental evidence that consuming beta-carotene enhances skin yellowness and redness. Second, we showed that there was a significant effect of beta-carotene supplementation on male facial attractiveness and perceived health.

Recent correlational studies have linked beta-carotene intake with increased skin yellowness Stephen et al. Our study provides the first evidence for a causal link between beta-carotene and these changes. To the extent that attractiveness affects mating success Rhodes et al.

According to the carotenoid trade-off hypothesis, coloration signals health because individuals face a trade-off between the use of available carotenoids in coloration versus supporting health.

The assumption that carotenoids affect health has been tested experimentally in numerous species of birds, fishes, lizards, and even insects, but the results have been equivocal Aguilera and Amat ; Blount et al. For humans, we found that although beta-carotene made the participants look healthier, there was no evidence that it enhanced actual health.

Beta-carotene supplementation did not affect innate immune function, oxidative stress, or semen quality, all measures that have been linked theoretically to the proposed antioxidant capacity of carotenoids.

Moreover, for each aspect of health, we used multiple measures, which should be superior to using single measures Adamo ; Halliwell and Whiteman Our results suggest that, rather than indicating actual health changes, the changes in perceived health due to beta-carotene supplementation may reflect an attractiveness halo effect Eagly et al.

It is possible that beta-carotene supplementation might have an effect on health in a population that is under greater physiological health stress or greater dietary restrictions than our sample.

From a life-history perspective, physiological trade-offs are more apparent when individual or environmental conditions are limiting Stearns Our participants were all relatively healthy individuals recruited from a university community.

It is possible that we found an effect of beta-carotene on facial appearance but not health because the participants simply did not require additional carotenoids to support their health and devoted all the supplemented beta-carotene to appearance. It would be informative for future studies to examine a population that is under greater physiological or dietary stress.

Although we did not find a significant effect of beta-carotene on any of our health measures, carotenoids could still be linked to health via indirect mechanisms.

For example, Hartley and Kennedy postulated that carotenoid coloration might actually signal the presence of other antioxidants that protect carotenoids from oxidative damage, which would otherwise cause carotenoids to lose their color i.

This hypothesis is also known as the carotenoid protection hypothesis. In support of this hypothesis, experimental studies have found that dietary supplementation of nonpigmentary antioxidants increase carotenoid-based coloration in species such as zebra finches, Taeniopygia guttata Bertrand et al.

It would be interesting to examine the carotenoid protection hypothesis in humans by investigating the effect of consuming nonpigmentary antioxidants on skin yellowness and redness. Another possibility is that carotenoids only affect health when they are paired with other nutrients.

Almbro et al. They argued that because vitamin E is converted to radical species when it is used as an antioxidant, beta-carotene might serve to recycle the radicalized vitamin E, thus enhancing overall antioxidant status. Therefore, a potential future direction would be to examine whether beta-carotene affects health in humans when paired with vitamin E.

In most species, carotenoid-based coloration is sexually selected via female mate choice for male carotenoid ornamentation, and most species show sexual dimorphism in carotenoid coloration.

A recent study reported that human skin color is also sexually dimorphic Carrito et al. However, mate selection in humans occurs in both directions and carotenoids influence appearance in both sexes Stephen et al. Therefore, it would be interesting to see the extent to which our findings could be replicated in women.

It would also be interesting for future studies to examine whether beta-carotene influences health over a longer supplementation period. We chose the week duration partly because spermatogenesis plus epididymal transit in humans takes a total of 82 days ~ Therefore, we should have been able to observe any effects of beta-carotene on semen quality after 12 weeks of supplementation.

Previous studies examining the effects of antioxidant supplementation on semen quality and oxidative stress have used similar supplementation durations Møller and Loft ; Showell et al.

However, it remains possible that we might observe significant effects of beta-carotene on health in a relatively healthy population like the one in the present study with a longer supplementation duration.

Zareba et al. Given this finding, it would be interesting to examine the long-term effect of beta-carotene supplementation on health by repeating the present study with a supplementation period of 1 year or more. In summary, we report the first double-blind, placebo-controlled experimental study on the effect of carotenoids on human facial appearance and health.

We found that beta-carotene alters skin color by enhancing yellowness and redness to enhance facial attractiveness in human males. However, we found no evidence that carotenoids improve actual health. Together, our results suggest that carotenoid-based coloration may have been sexually selected in humans, but we have no evidence to suggest that it is an honest signal of health.

Prevention

Individuals preferred faces that were transformed to be high in carotenoid color over low-carotenoid-color versions of the same faces Lefevre et al. Skin yellowness is also related to attractiveness of own-race faces for both Caucasian and African participants Stephen et al.

Facial yellowness is also related to how healthy faces appear, which is closely linked to attractiveness Rhodes et al. Both Caucasian and African participants increased yellowness in own-race face images when asked to adjust the color to make the faces look healthier Stephen et al.

There are, however, several limitations in the human carotenoid signaling literature. The evidence relating carotenoids to human facial appearance is almost entirely correlational, which prevents conclusions of causation.

Two studies reported that participants given daily beta-carotene supplements for 8 weeks showed an increase in skin yellowness and redness Stephen et al.

However, due to the lack of a control group in both studies, we cannot exclude the possibility that the observed color changes were due to factors other than beta-carotene supplementation. Furthermore, both studies had a very small sample size of 10, which makes it difficult to draw firm conclusions.

Tan et al. However, we cannot be certain that the effect was due to carotenoids and not to other nutrients in the smoothies. No studies have tested experimentally the effects of carotenoids on attractiveness and perceived health. Most importantly, no experimental study has tested whether carotenoids improve actual health as predicted by the carotenoid trade-off hypothesis.

Here we use a randomized, double-blind, placebo-controlled supplementation study to investigate the effects of beta-carotene on facial appearance and health in humans. We focus our study on female preferences for male appearance. First, we establish the effect of carotenoids on face color.

Based on previous findings Stephen et al. Second, we examine the effect of beta-carotene on attractiveness. We hypothesize that beta-carotene supplementation will enhance facial attractiveness.

Together, the 2 hypothesized results would support the idea that carotenoids play a role in human sexual selection by altering skin color. Third, we examine the effect of beta-carotene on healthy appearance. Based on previous findings that skin yellowness is positively correlated with perceived health Stephen et al.

Finally, we examine whether beta-carotene enhances actual health. We investigate a range of physiological health measures that are theoretically linked to carotenoids, including oxidative stress, innate immune function, and semen quality.

A positive effect of beta-carotene on any of these health measures would support the idea that carotenoid coloration is an honest signal of health. The study was approved by the Human Ethics Committee at the University of Western Australia Ethics approval ref.

All participants provided written consent prior to their participation in the project. Each of them received either course credit or transport remuneration. All of them identified themselves as heterosexual and reported that they did not suffer from any immunological, endocrine, or metabolic disorders.

Two previous studies that investigated the effect of beta-carotene supplementation on skin color have found significant changes in skin color after 8 weeks of beta-carotene supplementation with 10 participants and neither study had a placebo condition Stephen et al.

We also had a placebo group consisting of an additional 20 male participants. Participants first attended a 1. They were asked to refrain from consuming any food or flavored drinks 1 h before the session, not wear any make-up or tanning agents, and be clean-shaven.

Urine 10 mL was first collected in a sterile bottle for oxidative stress measures. Saliva 5 mL was then collected for immune function measures. Participants collected the saliva in a sterile bottle using the passive drool method after rinsing their mouth with water and waiting approximately 15 min.

Participants were seated at a fixed distance cm from the camera against a grey fabric background. A cape in the same grey fabric was draped over the participants to control for the color of their clothing.

Spectacles were removed and fringes covering the forehead were pulled back using a hairband. At the end of the laboratory session, the participants were given written instructions for semen collection, a sterile sample vial to collect the ejaculate, an ejaculate questionnaire, a piece of aluminum foil, and 4 pictures, each containing the front view image of a naked woman from Thornhill and Grammer They were asked to abstain from any ejaculation for 2—6 days before collecting the sample at home via masturbation while viewing the 4 images.

The images provided visual stimulation, which is necessary for the production of a normal ejaculate Wylie and Pacey Participants were asked to deliver the sample to the laboratory within 1 h of collection. During delivery, they were asked to wrap the sample vial in aluminum foil and place it under their arm or between their legs to maintain its temperature.

Participants also returned the completed ejaculate questionnaire, which noted the time at which the sample was collected, whether the entire ejaculate was collected and if not, the percentage and portion initial, middle, or end lost, and the time since their previous ejaculation.

To ensure double blinding, both capsule types were stored in identical opaque bottles with tamper evident seals that were broken only by the participants. The bottles were randomly assigned and coded by a research assistant who was not involved in the study.

The participants returned after 12 weeks for the post-supplementation follow-up, where the photography and sample collection were repeated.

The week supplementation period was chosen because human spermatogenesis takes around 74 days and epididymal transit takes an additional 8 days, making a total of 82 days ~ To control for random fluctuations in lighting conditions and camera settings, the photos were color-calibrated by standardizing the color of the ColourChecker patches based on known CIELab values using the color calibration plugin in the program Psychomorph Tiddeman and Perrett The measurements were taken from ten 60 × 60 pixels squares.

Two squares were placed above each eyebrow on the forehead. Three squares were placed on each side of the cheek. Care was taken to avoid skin regions with blemishes, specular highlights, or shadows.

The CIELab values were averaged across the 10 squares to derive average lightness, redness, and yellowness values for each face.

We compared the attractiveness and perceived health of the pre- and post-supplementation color-calibrated faces using a 2-alternative forced-choice procedure. In each trial, raters saw the pre- and post-supplementation faces of each male participant presented side by side on a computer screen.

Raters had to select the more attractive or healthy looking face. Each face pair remained onscreen until the rater responded.

Each task consisted of 2 blocks. All 43 male face pairs were presented twice, once in each block, making a total of 86 trials for each task. In block 1, the post-supplementation face was shown on the right for half the face pairs.

The face pairs were presented again in block 2 in the opposite left-right orientation. Block order was counterbalanced across participants. All faces were rotated and aligned so that the eyes were lying on a horizontal plane at the same height.

All images were cropped to × pixels and a black oval mask was applied to cover most of the hair, ears, and neck. An attractiveness score for each face pair was calculated as the percentage of times the post-supplementation face was chosen as the more attractive face.

A perceived health score for each face pair was calculated as the percentage of times the post-supplementation face was chosen as the more healthy looking face.

However, several previous studies have investigated skin color preferences using online samples Lefevre et al. Both samples showed a preference for high carotenoid skin color, with no difference in the preference between the two. This finding suggests that any additional noise due to uncalibrated monitors is relatively small compared to the color variation among the faces.

Markers of DNA oxidation 8-OHdG and lipid peroxidation isoprostane were analyzed in duplicates using competitive enzyme-linked immunoassay ELISA kits from Northwest Life Science Specialties Vancouver, VA. A significant proportion of urinary isoprostane is conjugated to glucoronic acid, which is not assayable Yan et al.

To obtain a more accurate measure of overall isoprostane level, µL of each sample was incubated with 5 µL of beta-glucoronidase for 2 h at 37°C to cleave and free the isoprostanes from their conjugated forms before running the isoprostane assays.

Creatinine was determined in duplicates using colorimetric assay kits from Northwest Life Science Specialties Vancouver.

Salivary bacteria killing capacity against Escherichia coli ATCC no. Salivary supernatant was incubated with E. coli for 30 min to facilitate bacteria killing, and then incubated overnight on trypticase soy agar TSA plates to quantify the amount of bacteria remaining see Supplementary Material for details.

Images of the plates were taken together with a ruler as a size reference. We used the program ImageJ to measure the following: total number of colonies in each plate, average area of each colony, and total area of the colonies combined. Bacteria killing capacity was calculated as the percentage difference in colony number relative to positive controls.

Bacteria growth suppression capacity was calculated as the percentage difference in average colony area relative to positive controls. Overall salivary immunity was calculated as the percentage difference in total colony area relative to positive controls. A lysoplate assay was used to determine salivary lysozyme activity.

Micrococcus lysodeikticus ATCC no. Ten microlitres of whole saliva from each sample were added to 80μL of M. lysodeikticus in duplicates in a well plate. Positive controls containing 10 μL of PBS and 80 μL of M.

lysodeikticus were also added to the plate in duplicates. The plate was incubated at 33°C for 10 min and the absorbance was measured using an M5 SpectraMax microplate reader Molecular Devices, Sunnyvale, CA. Salivary lysozyme activity was calculated as the difference in absorbance between the sample wells and the positive controls.

The semen samples were analyzed in 6 replicates immediately upon delivery using the Hamilton-Thorne CEROS Computer Assisted Semen Analysis CASA system Simmons et al. The system measures total sperm concentration, percentage motile sperm and 7 motility related variables.

Seven samples had to be diluted because they were too concentrated for the CASA to analyze see Supplementary Material for details. A portion of the post-supplementation semen sample was stored in accordance with McEvoy et al.

The semen DNA fragmentation level of each sample is measured by the percentage of fragmented sperm cells see supplementary material for details. Principal components analysis PCA was used to summarize the inter-related semen quality data and immune function data.

PC1 was weighted most strongly by bacterial killing and suppression capacity. PC2 was weighted most strongly by lysozyme activity and overall bacteria immunity.

PC1 was weighted most strongly by variables related to rapid progressive motility. PC2 was weighted most strongly by variables related to the linearity of the sperm movement. PC3 was weighted most strongly by high sperm concentration and percentage motile sperm with low levels of left-right head movement.

PC3 was found to be influenced by variation in the collection procedure and abnormalities in the sample WHO see Supplementary Material for details. Therefore, we ran all analyses for PC3 on the residuals after accounting for these variables.

Difference scores were calculated for each of the 3 skin color variables yellowness, redness, and lightness , the 2 oxidative stress measures 8-OHdG and isoprostane , the 2 immune function PCs, and the 3 semen quality PCs, by subtracting the pre-supplementation scores from the post-supplementation scores.

The descriptive statistics for the dependent variables, including all the difference scores, 2-alternative forced-choice attractiveness scores, 2-alternative forced-choice perceived health scores, and post-supplementation sperm DNA fragmentation levels are presented in Table 1.

Positive values indicate an increase in a particular measure post-supplementation. During data analysis, the treatment conditions were binary coded to prevent any experimenter biases and the code was broken only after the statistical analyses were finalized.

All variables are presented as pre—post difference scores indicated by Δ with the exception of the 2-alternative forced-choice attractiveness and perceived health scores, which were scored based on the percentage of times the post-supplementation face of a participant was chosen as more attractive or healthy looking, respectively, and the sperm DNA fragmentation levels, which was measured post-supplementation.

One-way Anovas with Treatment beta-carotene, placebo as the between-participants factor were conducted for all the dependent variables, including each of the skin color difference scores yellowness, redness, and lightness , the 2-alternative forced-choice attractiveness score, the 2-alternative forced-choice perceived health score, each of the oxidative stress difference scores, each of the immune function PC difference scores, each of the semen quality PC difference scores and the post-supplementation sperm DNA fragmentation levels.

All residuals were normally distributed. These results indicate that the Treatment effect was due to an increase in yellowness in the beta-carotene group. These results show that, as predicted, beta-carotene supplementation significantly increased face yellowness and redness but not lightness.

Examples of the color variation between pre- and post-supplementation for the beta-carotene and placebo groups are shown in Figure 2. Boxplots of pre-post changes in skin yellowness, redness, and lightness by Treatment beta-carotene vs placebo.

Examples of color variation between pre- and post-supplementation by Treatment condition. Thus beta-carotene supplementation significantly enhanced facial attractiveness. Boxplots of 2-alternative-forced-choice scores for attractiveness and perceived health by Treatment beta-carotene vs placebo.

Thus beta-carotene supplementation significantly enhanced perceived health. We provide experimental evidence that the carotenoid beta-carotene enhances skin yellowness and redness and increases facial attractiveness in human males. Contrary to the carotenoid trade-off hypothesis, we did not find any effect of beta-carotene on measures of oxidative stress, immune function, semen quality, or sperm DNA fragmentation.

Thus, despite the effects of beta-carotene on facial appearance, we find no evidence that carotenoid-related skin color is an honest signal of health in human males. Carotenoid-based coloration has been shown to influence mate choice in taxa such as birds, fishes, and lizards Endler ; Kodric-Brown ; Olson and Owens ; Møller et al.

Our results suggest that carotenoid-based coloration also serves mate choice functions in humans. First, using a randomized, double-blind, placebo-controlled experimental design, we provide strong experimental evidence that consuming beta-carotene enhances skin yellowness and redness.

Second, we showed that there was a significant effect of beta-carotene supplementation on male facial attractiveness and perceived health. Recent correlational studies have linked beta-carotene intake with increased skin yellowness Stephen et al.

Our study provides the first evidence for a causal link between beta-carotene and these changes. To the extent that attractiveness affects mating success Rhodes et al.

According to the carotenoid trade-off hypothesis, coloration signals health because individuals face a trade-off between the use of available carotenoids in coloration versus supporting health. The assumption that carotenoids affect health has been tested experimentally in numerous species of birds, fishes, lizards, and even insects, but the results have been equivocal Aguilera and Amat ; Blount et al.

For humans, we found that although beta-carotene made the participants look healthier, there was no evidence that it enhanced actual health. Beta-carotene supplementation did not affect innate immune function, oxidative stress, or semen quality, all measures that have been linked theoretically to the proposed antioxidant capacity of carotenoids.

Moreover, for each aspect of health, we used multiple measures, which should be superior to using single measures Adamo ; Halliwell and Whiteman Our results suggest that, rather than indicating actual health changes, the changes in perceived health due to beta-carotene supplementation may reflect an attractiveness halo effect Eagly et al.

It is possible that beta-carotene supplementation might have an effect on health in a population that is under greater physiological health stress or greater dietary restrictions than our sample. From a life-history perspective, physiological trade-offs are more apparent when individual or environmental conditions are limiting Stearns Our participants were all relatively healthy individuals recruited from a university community.

It is possible that we found an effect of beta-carotene on facial appearance but not health because the participants simply did not require additional carotenoids to support their health and devoted all the supplemented beta-carotene to appearance.

It would be informative for future studies to examine a population that is under greater physiological or dietary stress. Although we did not find a significant effect of beta-carotene on any of our health measures, carotenoids could still be linked to health via indirect mechanisms.

For example, Hartley and Kennedy postulated that carotenoid coloration might actually signal the presence of other antioxidants that protect carotenoids from oxidative damage, which would otherwise cause carotenoids to lose their color i. This hypothesis is also known as the carotenoid protection hypothesis.

In support of this hypothesis, experimental studies have found that dietary supplementation of nonpigmentary antioxidants increase carotenoid-based coloration in species such as zebra finches, Taeniopygia guttata Bertrand et al. It would be interesting to examine the carotenoid protection hypothesis in humans by investigating the effect of consuming nonpigmentary antioxidants on skin yellowness and redness.

Another possibility is that carotenoids only affect health when they are paired with other nutrients. Almbro et al. They argued that because vitamin E is converted to radical species when it is used as an antioxidant, beta-carotene might serve to recycle the radicalized vitamin E, thus enhancing overall antioxidant status.

Therefore, a potential future direction would be to examine whether beta-carotene affects health in humans when paired with vitamin E. In most species, carotenoid-based coloration is sexually selected via female mate choice for male carotenoid ornamentation, and most species show sexual dimorphism in carotenoid coloration.

A recent study reported that human skin color is also sexually dimorphic Carrito et al. However, mate selection in humans occurs in both directions and carotenoids influence appearance in both sexes Stephen et al. Therefore, it would be interesting to see the extent to which our findings could be replicated in women.

It would also be interesting for future studies to examine whether beta-carotene influences health over a longer supplementation period. We chose the week duration partly because spermatogenesis plus epididymal transit in humans takes a total of 82 days ~ Therefore, we should have been able to observe any effects of beta-carotene on semen quality after 12 weeks of supplementation.

Previous studies examining the effects of antioxidant supplementation on semen quality and oxidative stress have used similar supplementation durations Møller and Loft ; Showell et al.

However, it remains possible that we might observe significant effects of beta-carotene on health in a relatively healthy population like the one in the present study with a longer supplementation duration. Zareba et al. Given this finding, it would be interesting to examine the long-term effect of beta-carotene supplementation on health by repeating the present study with a supplementation period of 1 year or more.

In summary, we report the first double-blind, placebo-controlled experimental study on the effect of carotenoids on human facial appearance and health. We found that beta-carotene alters skin color by enhancing yellowness and redness to enhance facial attractiveness in human males.

However, we found no evidence that carotenoids improve actual health. Together, our results suggest that carotenoid-based coloration may have been sexually selected in humans, but we have no evidence to suggest that it is an honest signal of health.

Seek Shade : During peak sun hours usually between 10 a. and 4 p. Cover Up : Wear protective clothing, such as wide-brimmed hats, long-sleeved shirts, and sunglasses with UV protection.

Avoid Tanning Beds : Tanning beds emit harmful UV radiation, increasing the risk of skin cancer and premature aging. It is best to avoid them completely. Stay Hydrated : Drink plenty of water to keep your skin hydrated, as well-hydrated skin is better able to protect itself from damage.

Sun Smart : Be aware of your skin type and sun sensitivity. Individuals with fair skin and a history of sunburn or skin cancer should take extra precautions.

Anti-aging and skin regeneration are key parts of skincare that attempt to keep skin looking young and address signs of aging. Sun exposure, lifestyle choices, genetics, and the natural aging process all contribute to changes in the look of the skin over time. Here are several anti-aging and skin rejuvenation methods:.

Sun Protection : One of the most important steps in anti-aging is protecting your skin from harmful UV rays. UV rays hasten skin aging, causing wrinkles, fine lines, hyperpigmentation, and loss of elasticity. To avoid UV damage, apply broad-spectrum sunscreen with an SPF of 30 or higher every day, seek shade when the sun is at its strongest, and wear protective clothing.

Active Ingredients in Skincare : Include skincare products with active ingredients known to promote skin rejuvenation and collagen production. The following are some common anti-aging ingredients:. Retinoids : These vitamin A derivatives have been shown in clinical studies to reduce the appearance of wrinkles, increase collagen production, and improve skin texture.

Vitamin C : A powerful antioxidant that helps brighten the skin, even out skin tone, and stimulate collagen synthesis. Peptides : Short chains of amino acids that may aid in collagen production and skin firmness. Hyaluronic Acid : A hydrating ingredient that helps the skin retain moisture, reducing the appearance of fine lines and plumping it.

Glycolic Acid and Alpha Hydroxy Acids AHAs : Alpha hydroxy acids AHAs exfoliate the skin, promoting cell turnover and improving skin texture. Hydration and moisturization : Keeping the skin hydrated is critical for maintaining its elasticity and plumpness.

Use moisturizers that are appropriate for your skin type to lock in moisture and prevent dryness. Healthy Eating : A well-balanced diet full of vitamins, minerals, and antioxidants supports the health of the skin.

Fruits, vegetables, and nuts are examples of foods high in antioxidants that can help fight free radicals and lessen oxidative stress on the skin. Hydration from Within : Keep your body and skin hydrated by drinking plenty of water.

Hydration is essential for a healthy, radiant complexion. Lifestyle Choices : Avoid smoking and limit alcohol consumption, as smoking and excessive alcohol intake can accelerate skin aging and cause premature wrinkles.

Sleep and Stress Management : Getting enough quality sleep and managing stress is essential for skin rejuvenation. Lack of sleep and chronic stress can cause increased inflammation and affect the appearance of the skin.

Professional Treatments : Depending on your skin's specific needs and concerns, seek the advice of a dermatologist or licensed skincare professional before undergoing treatments such as chemical peels, microdermabrasion, laser therapy, or dermal fillers.

Incorporating beta-carotene into your skincare routine can help you achieve a radiant complexion while also promoting skin health. Here are some ideas for incorporating beta-carotene into your daily skincare routine:. Choose Beta-Carotene-Rich Skincare Products : Look for beta-carotene-containing skincare products or plant extracts that contain this compound.

Serums, moisturizers, facial oils, and masks are examples of such products. Check the labels to see if beta-carotene is listed as an active ingredient. Consider Using a Beta-Carotene Face Oil : Incorporate a beta-carotene-infused face oil into your routine. These oils can be applied to the skin after cleansing and before moisturizing to deliver a concentrated dose of beta-carotene and other beneficial nutrients.

Apply a Beta-Carotene Serum : Beta-carotene serums can be applied before your regular moisturizer. They are light and easily absorbed, making them appropriate for daily use. Beta-carotene-containing serums can help protect the skin from free radicals and promote a more radiant complexion.

Incorporate a Beta-Carotene Mask : Incorporate a beta-carotene-rich mask into your weekly skincare routine. Masks can give your skin an extra boost of antioxidants and hydration. Eat Beta-Carotene-Rich Foods : In addition to topical applications, eating beta-carotene-rich foods can help your skin from the inside out.

Include carrots, sweet potatoes, pumpkin, mangoes, and leafy greens in your diet. These foods not only provide beta-carotene but also offer a range of other beneficial nutrients for skin health.

Consider Supplements : If you have a vitamin A deficiency or find it difficult to consume enough beta-carotene-rich foods, consult your doctor about beta-carotene supplements. However, it's essential to follow their advice and recommended dosage, as excessive vitamin A intake can have adverse effects.

Perform a Patch Test : A patch test is required before incorporating any new skincare product into your routine, including beta-carotene-containing products.

Apply a small amount of the product to a small area of your skin such as the inner wrist and wait at least 24 hours for any adverse reactions, such as redness or irritation. Combine with Other Antioxidants : Combine beta-carotene with other antioxidants such as vitamin C and vitamin E.

These antioxidants work together to boost each other's ability to protect the skin from free radicals. Topical beta-carotene treatment can help promote skin health and address specific skin issues. Because beta-carotene is a potent antioxidant and a precursor to vitamin A, it is useful in skincare.

Here's how to utilize topical beta-carotene and what it can do for you:. Antioxidant Protection : When applied topically, beta-carotene acts as an antioxidant, helping to neutralize free radicals in the skin. This shields the skin from oxidative stress caused by environmental aggressors such as UV radiation, pollution, and other pollutants.

Anti-Aging : As an antioxidant, beta-carotene can help reduce the signs of aging by combating free radicals that contribute to premature aging, such as wrinkles, fine lines, and loss of skin elasticity. Skin Rejuvenation : Beta-carotene promotes skin cell turnover, which can result in a more youthful and radiant complexion.

It aids in the removal of dead skin cells and the growth of new, healthy cells. UV Protection : Although not a replacement for sunscreen, topical beta-carotene may provide additional protection against the harmful effects of UV radiation when combined with other antioxidants.

Soothing and Calming : Because beta-carotene has anti-inflammatory properties, it can be used to soothe and calm irritated or inflamed skin. It may be beneficial to those who have sensitive or acne-prone skin. Brightening and Even-Toning : By reducing hyperpigmentation and dark spots, beta-carotene can help to achieve a brighter and more even skin tone.

Hydration : Some beta-carotene-containing topical formulations may have moisturizing properties that help keep the skin hydrated and nourished. Beta-carotene is a naturally occurring molecule that can be found in a variety of fruits and vegetables.

Incorporating these foods into your diet can provide you with a sufficient amount of beta-carotene. Carrots, sweet potatoes, pumpkins, mangoes, apricots, spinach, kale, butternut squash, red bell peppers, melons, papayas, broccoli, tomatoes, collard greens, and peas are all high in beta-carotene.

Keep in mind that cooking can reduce the beta-carotene content of some foods. Consider steaming or lightly heating veggies instead of boiling them for long periods of time to maintain their nutritional content.

Incorporating a range of these beta-carotene-rich foods into your diet can bring a multitude of health benefits, including improved skin health, antioxidant protection, and general well-being. While beta-carotene in food is generally safe and well-tolerated, high-dose beta-carotene supplements may have potential side effects and safety concerns.

Here are some things to keep in mind when taking beta-carotene supplements:. Carotenosis Skin Discoloration : Excessive beta-carotene intake, typically through supplements, can cause carotenosis, a harmless condition.

This condition causes the skin to turn yellow or orange, especially in areas with thicker skin, such as the palms and soles. It can also affect other parts of the body, including the face.

Carotenosis is usually reversible if the amount of beta-carotene consumed is reduced. Medications : High-dose beta-carotene supplements may interact with some medications. For example, beta-carotene supplements may interfere with the absorption of certain fat-soluble drugs, such as cholesterol-lowering medications and some anti-inflammatory drugs.

Increased Lung Cancer Risk in Smokers : Some studies have suggested that high-dose beta-carotene supplementation may increase the risk of lung cancer in smokers or people exposed to asbestos. As a result, beta-carotene supplements are not recommended for smokers or people who have smoked in the past.

Pregnancy and Breastfeeding : Pregnant and breastfeeding women should avoid taking high-dose beta-carotene supplements unless their healthcare provider specifically recommends it.

Excessive vitamin A intake, including beta-carotene, has been linked to foetal harm. Allergies : Some people are allergic to beta-carotene or other carotenoids. If you notice any signs of an allergic reaction, such as itching, swelling, or difficulty breathing, discontinue use of the product immediately and seek medical attention.

Gastrointestinal Disturbances : High doses of beta-carotene supplements may cause nausea, diarrhea, and stomach cramps in some people. To reduce the possibility of side effects and ensure safe use:.

Stick to beta-carotene obtained from natural food sources rather than supplements. If you want to take beta-carotene supplements, talk to your doctor first, especially if you have any pre-existing health conditions or are taking medications.

Follow your healthcare provider's or the product's dosage recommendations. Avoid high-dose supplements because a well-balanced diet usually provides enough beta-carotene for most people. It is critical to prioritise a nutritious diet rich in nutrients, such as beta-carotene-rich fruits and vegetables.

Dietary beta-carotene is generally safe and provides several health advantages without the risk of overconsumption or unfavorable side effects. Before beginning any new supplement regimen, always visit a healthcare expert, especially if you have specific health concerns or illnesses.

Excessive beta-carotene consumption, particularly through high-dose supplements, may pose hazards and have negative effects. It should be noted that these hazards are mostly related to supplementing with isolated beta-carotene rather than eating beta-carotene from natural dietary sources.

Excess beta-carotene consumption may cause skin discoloration carotenosis , medication interactions, an increased risk of lung cancer in smokers, harm to pregnant women, and gastrointestinal disturbances. To reduce the risks of excessive beta-carotene consumption:.

Beta-carotene is primarily obtained from natural food sources such as fruits and vegetables. If you choose to take beta-carotene supplements, make sure to follow your healthcare provider's or the product's instructions. High-dose supplements should be avoided unless specifically prescribed or recommended by a healthcare professional.

If you have any pre-existing health conditions or are taking medications, talk to your doctor before beginning any new supplement regimen. Remember that a well-balanced diet rich in colorful fruits and vegetables can provide enough beta-carotene for most people without the risks of excessive supplementation.

Prioritise a healthy and varied diet to promote overall health and well-being. To ensure proper and safe use of beta-carotene, whether from dietary sources or supplements, it is critical to follow safety guidelines.

Here are some precautions to take when using beta-carotene:. Obtain Beta-Carotene from Food Sources : Natural food sources are the safest way to incorporate beta-carotene into your diet. Consume beta-carotene-rich fruits and vegetables such as carrots, sweet potatoes, pumpkin, mangoes, spinach, and kale.

Excessive Supplement Use : High-dose beta-carotene supplements should be used with caution and only under the supervision of a healthcare professional. Excessive intake of isolated beta-carotene supplements can lead to potential side effects, including skin discoloration carotenosis and interactions with medications.

Consult a Healthcare Professional : Before beginning any new supplement regimen, including beta-carotene supplements, take an online dermatologist consultation , particularly if you have pre-existing health conditions or are taking medications.

Consider Your Individual Needs : The recommended daily intake of beta-carotene varies depending on age, gender, and individual health conditions.

Your healthcare provider can advise you on the best dosage for you. Avoid High Doses During Pregnancy : Pregnant women should avoid high-dose beta-carotene supplements because too much vitamin A can harm the developing foetus.

Monitor for Allergic Reactions : If you notice any signs of an allergic reaction after using beta-carotene-containing products, such as itching, swelling, or difficulty breathing, stop using them immediately and seek medical attention. Combine with Other Antioxidants : Beta-carotene collaborates with other antioxidants such as vitamin C and vitamin E.

Consider including a variety of antioxidant-rich foods and skincare products to maximize your benefits. Patch Test New Skincare Products : Before applying beta-carotene-containing skincare products to your entire face for the first time, perform a patch test on a small area of skin to check for any adverse reactions.

Prioritise a Balanced Diet : For most people, getting beta-carotene from a balanced diet is both safe and sufficient. Eat a variety of nutrient-rich foods, including colorful fruits and vegetables, to promote overall health and well-being. Avoid Smoking and High-Risk Populations : High-dose beta-carotene supplements are not recommended for smokers or people at high risk of lung cancer, as studies have shown an increased risk of lung cancer in these groups.

By following these precautions, you can enjoy the benefits of beta-carotene while also supporting your skin and overall health. Always seek personalized advice and recommendations from a healthcare professional when in doubt or if you have specific health concerns.

Because of its multiple skin health benefits, beta-carotene is a natural key to getting a bright complexion. Beta-carotene, as a provitamin A molecule and a potent antioxidant, is essential for enhancing skin brightness and overall well-being.

Here's how beta-carotene helps you look your best:. Antioxidant Protection : Beta-carotene neutralises free radicals, which are unstable molecules that can damage skin cells and contribute to premature aging.

By reducing oxidative stress, beta-carotene helps keep the skin looking youthful and radiant. UV Protection : Beta-carotene and other antioxidants can provide an additional defence against the damaging effects of UV radiation, though they cannot replace sunscreen.

It contributes to skin health and lowers the risk of sun-induced skin damage by battling free radicals produced by sun exposure. Skin Cell Turnover : Beta-carotene encourages skin cell turnover, which is necessary for preserving a young, radiant complexion.

The skin appears more youthful as new, healthy skin cells emerge from beneath the surface as older skin cells are shed. Even Skin Tone : Beta-carotene can help to reduce hyperpigmentation and even out skin tone, resulting in a complexion that is more uniform.

Soothing and Calming : Beta-carotene's anti-inflammatory properties can soothe and calm irritated or sensitive skin, promoting a healthier and calmer complexion.

Skin Rejuvenation : Beta-carotene contributes to skin rejuvenation by promoting collagen production and supporting skin renewal, reducing the appearance of fine lines and wrinkles.

Hydration and Moisturization : Some beta-carotene-containing topical products may have moisturizing properties, which help to keep the skin hydrated and supple.

Brightening Effect : Beta-carotene can give the skin a natural glow, making it appear brighter and more vibrant. Consider the following to reap the benefits of beta-carotene's effects on skin health and complexion:. Consume beta-carotene-rich foods such as carrots, sweet potatoes, mangoes, and leafy greens.

To provide topical support for your skin, use beta-carotene-containing skincare products or plant extracts rich in this nutrient. Combine beta-carotene with other antioxidants and nourishing skincare ingredients for maximum benefit. Use broad-spectrum sunscreen on a daily basis, seek shade during peak sun hours, and wear protective clothing.

Remember that achieving a radiant complexion is not solely dependent on one nutrient or skincare product. A comprehensive skincare regimen that includes a healthy diet, adequate hydration, sun protection, and a consistent skincare routine contributes to a glowing and healthy complexion.

Can Juicing Even Out Your Skin Tone?

Beta-carotene for skin -

They can be prescribed for different skin needs. At that point, the body turns them into retinol, with varying numbers of steps. Eventually, they morph into retinaldehyde before becoming retinoic acid.

All of the above esters can be found in skin care products. So, they are selected for particular strengths by cosmetic chemists. This is a pertinent question.

The thing is, retinoic acid is very strong stuff. In fact, even over-the-counter retinol is quite strong. Most people who use this vitamin for skin care can experience dryness, peeling and redness even if they start with oily, acneic skin.

It is very uncomfortable to use at first. Though, eventually the skin gets used to it for most people. Retinoids, in their stronger forms, and in higher concentrations, are only allowed to be sold with prescriptions in countries that regulate them, like Canada.

Pregnant women should not use them — not even topically. Oral Accutane isotretinoin can cause long-term side-effects throughout the body.

But of course, there are many benefits to using gentler, over-the-counter versions of retinoids for the average, everyday person. This is possible mainly with retinol.

People with sensitive skin may not be able to tolerate them at all. So, cosmetic researchers have come up with all kinds of ways to reduce irritation caused by retinol in skin care. These attempts have included:.

For example, one synthetic form of retinol which also undergoes steps to become retinoic acid, is retinyl retinoate.

It is purposely designed to oxidize slower, so that it can be less irritating to the skin. In another example, retinoic acid can be mixed with a vitamin C ester to become retinyl ascorbate.

Our favourite adaptation would be encapsulated retinol. Specifically, at our clinic, we sell Retinol Complex 1, 0. What is encapsulated retinol? The coating allows for two main actions:. These coatings can include moisturizers or antioxidants, like in the case with SkinMedica® retinol.

When it comes to retinol and not other forms of retinoids , almost anyone can benefit from this ingredient. That is, as long as they can tolerate its strength, and are diligent to wear high SPF sunscreen every day. This also applies to retinyl esters.

On your next product hunt, test a higher concentration, and again, gradually increase application until your skin is used to it. Our advice is to look for a retinol product that combines the benefits of other ingredients to reduce irritation while remaining effective, such as the encapsulated retinol by SkinMedica® mentioned above.

The product should also be free of irritants such as fragrances, drying alcohols or ingredients that attempt to further exfoliate the skin, such as alpha-hydroxy acids.

Now, when it comes to other retinoids , including prescription-strength retinol, the way to find out the best one for you , is to speak with your doctor. These are all available by prescription in North America with the exception of a low-strength adapalene which is available over the counter in the U.

Even if you think you need a mild strength of a prescription retinoid, a doctor will need to clear it first. Most people who are prescribed such strong versions of retinoids may have extreme skin conditions that require them. They may have more potential side-effects. But, whether the benefits outweigh their cons will be something for you and your doctor to determine.

So, they are not like ingesting vitamin A supplements, which you can have too much of. Now, it is important to be warned that vitamin A derivatives, like retinol and its esters, can make you sensitive to UV light. UV light exposure leads to free radical damage , which can — eventually — lead to skin cancers.

For that reason, vitamin A skin products should only be used at night. They should also be followed by the use of an SPF 30 or higher during the day. On the flip side, when used appropriately, vitamin A can help to remove precancerous, sun-damaged cells from your body.

Human skin is complex; it needs many antioxidants , growth factors , proteins, fats and hydrators among other things to supplement its ability to function and look good. No doubt, the skin care industry offers plenty of options for wrinkles and anti-aging needs.

Acne is another big category where the skin care industry thrives.
