The internet is full of promises for quick beauty fixes, but the viral ‘carrot tan’ trend may actually have some science behind it.
Millions of people are munching on raw carrots, hoping to swap pricey self-tanners and risky UV exposure for a natural, sun-safe glow.
Carrots and other produce contain plant pigments called carotenoids, especially beta-carotene, alpha-carotene, and lutein that may give skin a warmer, more radiant look.
To find out whether your body can absorb these fat-soluble compounds through the gut and carry them through the bloodstream to improve your skin, Daily Mail asked two health experts.
How These Pigments Affect Your Skin
Your body can’t turn all the carotenoids you eat into vitamin A at once, so the extra pigments can build up naturally in the skin’s outer layers.
A landmark St. Andrews study published in PLoS ONE found that even modest increases in fruit and vegetable intake can create noticeable, healthier-looking changes in skin color in as little as six weeks.
The researchers also confirmed that these changes come from carotenoid absorption, not melanin production.
For many healthy consumers, consistency of eating carrots over one to two months is necessary before expecting a noticeable shift in skin undertones, experts explained
‘A “carotenoid glow” is a real, measurable change in skin color caused largely by carotenoids from the diet accumulating in the skin,’ said Julia Zumpano, a registered dietitian with Cleveland Clinic in Ohio.
‘They accumulate particularly in the epidermis and superficial skin layers, which can cause the skin to look subtly more golden-yellow.’
In other words, those pigments change the way your skin reflects light, giving it a subtle golden hue that can easily be mistaken for a suntan, according to a study outlined in The New England Journal of Medicine.
How Much You Need and How Long It Takes
Achieving this subtle cosmetic shift does not require an extreme mega-dose of produce.
Clinical trials published from 2023 in the Journal of Nutrition show that consistent daily intake over a period of four to eight weeks is the standard timeframe required to observe visible skin alteration in most adults.
‘Based on several studies it appears that a range of 5 to 15 mg of carotenoids for four to eight weeks can provide a subtle carotenoid glow assuming a baseline varied diet,’ continued Zumpano.
In practical grocery terms, this target translates roughly to one to three medium carrots daily.
That said, how quickly carotenoids show up in your skin can vary quite a bit depending on your metabolism, usual diet, and any underlying health conditions.
‘These effects may appear more quickly and at smaller doses if you have a condition that affects or inhibits the natural breakdown or processing methods for beta carotene such as liver disease, diabetes, hypothyroidism, or anorexia,’ said Gabrielle Judd, a registered dietitian at Johns Hopkins Medicine in Baltimore.
For many healthy consumers, consistency over one to two months is necessary before expecting a noticeable shift in skin undertones, experts explained.
Instead of loading up on carrots alone, you can mix things up with other carotenoid-rich foods like sweet potatoes, pumpkin, butternut squash, mangoes, spinach and kale
Carrot Glow vs Sun Tanning: What Wins?
Despite a similar deepening in skin tone, a carotenoid glow and a regular UV tan are very different.
According to a 2026 study from Northwestern Medicine, sunbathing and tanning beds expose your skin to ultraviolet radiation, which can damage DNA, speed up visible aging, break down collagen, and raise your risk of melanoma and other skin cancers.
Judd told Daily Mail: ‘UV tanning is one of the most harmful processes for the skin, and repeated exposure can lead to the development of skin cancer.’
Dietary carotenoids, on the other hand, work more like a built-in defense system for your skin.
Once they make their way into skin tissue, they help neutralize free radicals and push back against oxidative damage from pollution and sun exposure.
‘Dietary carotenoid coloration gives a healthy golden glow and protects skin with antioxidants, which is a real anti-aging advantage,’ said Zumpano.
Instead of damaging the skin barrier, carotenoid-rich foods help strengthen it from the inside out.
Avoid Turning Orange: Radiance vs Carotenemia
While boosting your vegetable intake is overwhelmingly positive for your health, there is a clear boundary between a healthy radiance and an over-saturated orange discoloration known as carotenemia.
Carotenemia is a benign condition caused by excessive blood concentrations of beta-carotene that can result in a noticeably uneven skin tone.
‘Excess intake of the compound beta carotene, an amount beyond the body’s normal uses and functions, can lead to carotenemia or a buildup of these orange-hued antioxidant compounds,’ said Judd.
‘Most typically noticeable in areas with thicker skin like the palms or heel pads but it may also be seen in the face of those with fair complexions.’
To prevent your hands and feet from taking on an undesirable orange hue, the dietitians recommend moderation and dietary variety.
Instead of loading up on carrots alone, mix things up with other carotenoid-rich foods like sweet potatoes, pumpkin, butternut squash, mangoes, spinach, and kale throughout the week.
Eating one to three carrots a day may gradually bring out warm golden undertones, but it won’t turn fair skin-deep bronze overnight like self-tanners, our experts said
Kitchen Hacks to Boost Carotenoid Absorption
If you want to get more of the skin-friendly benefits from your produce, the way you prepare it really matters. Raw carrots have tough cell walls, so your digestive system has a harder time getting to all that beta-carotene.
‘Consuming beta carotene foods concurrently with a fat can help to improve the bioavailability of the nutrient,’ explained Judd. ‘Chopping and cooking the foods as opposed to eating them whole and raw also help to improve the bioavailability and thus absorption of the nutrient.’
When you combine cooking and healthy fats, absorption of beta-carotene and other carotenoids can increase by two to six times compared to eating raw carrots without fat, Zumpano also said.
A simple culinary hack is roasting sliced carrots or sweet potatoes in olive oil, or pairing raw carrot sticks with avocado dip or hummus made with tahini.
The Takeaway
Here’s the bottom line: the viral ‘carrot tan’ isn’t a glow-up you’ll get overnight. Think of it as a healthy little perk of eating a nutrient-packed diet, not a stand-in for a real tan or cosmetic products.
Eating one to three carrots a day may gradually bring out warmer, golden undertones, support hydration, and give your body a boost of protective antioxidants, but it won’t turn fair skin-deep bronze overnight.
‘What’s true is that eating a carotenoid-rich diet can make the skin look healthier, but the exaggerated claim of getting a tan, transformed skin, or radiantly glowing skin overnight by just eating carrots is hype,’ said Zumpano.
‘Consume a balanced diet rich in phytonutrients and antioxidants for overall health, not just appearance.’
More importantly, maintaining realistic expectations is essential when evaluating viral wellness trends.
‘I am all for hype that gets people eating more fruits and vegetables, but it is all about having realistic expectations and always thinking if something sounds too good to be true, it often is,’ cautioned Judd.
