The vitamins for glowing skin with the best evidence are vitamin C and vitamin E, ideally taken together, plus carotenoids from foods like cooked tomatoes. Many of the strongest skin results, though, come from creams such as retinoids and vitamin C serums, not pills. Supplements help most where your diet falls short, and for most Filipino adults, vitamin C intake does.
Key takeaways
- Your body needs vitamin C to build stable collagen, but in human trials, vitamin C pills alone didn't make skin more resistant to sunburn.
- Vitamins C and E taken together have shown more UV protection than either one alone.
- The vitamin A with proven skin results is a cream (retinoids), not an oral capsule.
- In FNRI's 2013 national survey, 98% of Filipino adults aged 19–49 ate less vitamin C than they need.
- No vitamin replaces daily sunscreen.
What makes skin "glow", and can vitamins help?
"Glowing" skin usually means an even tone, a smooth surface and a healthy, moisturised barrier. Vitamins play real roles in all three. Vitamin C, for example, is found at high levels in skin and is needed to make collagen, the protein that keeps skin firm and stable (Linus Pauling Institute).
The catch: much of the best evidence comes from creams and serums. Oral vitamins help most when your diet is short of a nutrient to begin with.
Are Filipinos getting enough skin vitamins?
For vitamin C, most aren't. FNRI's 2013 National Nutrition Survey recorded what more than 20,000 adults ate. Among adults aged 19–49, 98% had vitamin C intakes below the estimated average requirement, as did 54% for vitamin A and 14% for zinc. Average vitamin C intake was about 23mg a day, less than half the 52–60mg requirement, and fewer than 1 in 4 adults ate fruit on the survey day (Angeles-Agdeppa et al., Nutrition Journal, 2019).

"Inadequate intake" isn't a deficiency diagnosis, the survey didn't count supplements, and the analysis was co-funded by Nestlé Research. Still, a 2026 conference analysis of the 2018–2019 and 2021 surveys found vitamin C inadequacy stayed above 90% (Population Medicine, 2026).
Which vitamins for glowing skin have the best evidence?
Vitamin C: collagen support and sun defence
Taking vitamin C by mouth raises vitamin C levels in skin, but only up to a point: once blood levels are saturated, skin levels stop rising. Diets higher in vitamin C are linked with fewer wrinkles, but in two human trials, oral vitamin C alone didn't raise the amount of UV needed to redden skin (Linus Pauling Institute).
Topical vitamin C has stronger results: serums at 3–10% used for at least 12 weeks reduced wrinkling in several trials. If you're taking collagen, our guide to why collagen and vitamin C are paired explains how the two work together.
Vitamin E: works best alongside C
Several studies found that taking vitamins C and E together raised skin's sunburn threshold and reduced redness after UV exposure, while vitamin C alone did not (Linus Pauling Institute). For more on how antioxidants defend skin, see antioxidants and your skin.
Vitamin A: the cream, not the capsule
Retinoids, vitamin A creams such as tretinoin and retinol, have some of the best evidence in skincare. Used for months, they improve fine wrinkles, roughness and uneven pigmentation (Linus Pauling Institute). Oral retinoids are prescription medicines that need a doctor's supervision, so a high-dose vitamin A supplement isn't a shortcut. Get vitamin A from food.
Tomato carotenoids: promising, still early
Carotenoids are the pigments in coloured fruit and vegetables. In a UK trial, 20 women who ate 55g of tomato paste (16mg lycopene) with olive oil daily for 12 weeks needed more UV to show measurable reddening than women who had olive oil alone (Rizwan et al., British Journal of Dermatology, 2011). The sample was small, the women had very fair skin that burns easily, and the standard sunburn measure didn't differ significantly.
Colourless tomato carotenoids (phytoene and phytofluene) are less studied. In a 2022 study, 60 women aged 35–55 who took a tomato-carotenoid supplement for 12 weeks reported brighter, more even-looking skin, but those results were self-assessed rather than clinically measured (Journal of Cosmetic Dermatology, 2022).
| Nutrient | Best-studied form | Everyday food sources |
|---|---|---|
| Vitamin C | Serum; food or supplement | Bayabas, kalamansi, papaya |
| Vitamin E | Oral, with vitamin C | Nuts, seeds, vegetable oils |
| Vitamin A | Topical retinoids | Kalabasa, carrots, malunggay |
| Lycopene | Cooked tomato products | Tomato paste, cooked tomatoes |
Which skin vitamins are overhyped?
Biotin. It's in many hair, skin and nail products, but the NIH notes little scientific evidence for these uses, and high doses can cause false results in some lab tests (NIH Office of Dietary Supplements).
Glutathione. Popular, but the evidence is mixed and safety matters, especially for injectables. See glutathione for skin brightening: the science and safety.
What actually helps skin look bright under the Philippine sun?
- Wear sunscreen every day. Vitamin C isn't a sunscreen because it doesn't absorb UV light, and nothing you swallow replaces one.
- Close the vitamin C gap with food first (see the table above).
- Eat coloured vegetables and cooked tomatoes, ideally with a little oil.
- Use topical actives for specific concerns. For stubborn dark spots, see why dark spots won't fade under the Philippine sun or a dermatologist.
- Then use supplements to fill gaps, not to replace the steps above.
Where do skin supplements fit?
The Purest Co makes two supplements built around these ingredients. Snow Tomato Glowjuice contains 500mg White Tomato Extract, 100mg Acerola Extract (25% vitamin C), 100mg L-Cysteine and 15mg CoQ10 per serving, taken as 1–2 sachets a day. It's designed to support an even, bright-looking complexion. The tomato studies above used different preparations and doses, so they don't prove what this drink does.
Skin Snow Pre+Probiotic Melts combine 500M CFU Bifidobacterium lactis with 180mg Crassocephalum Rabens Extract, 10mg French Melon Extract and 18mg Vitamin C per sachet, for those interested in the gut-skin connection. Both are FDA Philippines-registered. The glowjuice contains animal-derived ingredients and the melts contain milk.
Frequently asked questions
What is the best vitamin for glowing skin?
Vitamin C has the broadest support. Your body needs it to build stable collagen, it acts as an antioxidant in skin, and most Filipino adults don't get enough from food. Its sun-protection effect appears stronger with vitamin E. For fine lines and uneven tone, topical vitamin C or a retinoid cream has stronger evidence than any supplement.
Can vitamins replace sunscreen?
No. Vitamin C doesn't absorb UV light, so it isn't a sunscreen. In human trials, oral vitamin C alone didn't raise the amount of UV it took to redden skin. Combinations of vitamins C and E and tomato carotenoids showed modest protection in small studies, but nothing you swallow comes close to daily broad-spectrum sunscreen.
How long do skin vitamins take to show results?
Plan on about three months. The tomato paste and tomato carotenoid studies both ran for 12 weeks, and topical vitamin C trials lasted at least 12 weeks too. Skin renews itself slowly, so give any change, whether diet, supplement or serum, a consistent trial of two to three months before judging it.
Is it safe to take several skin supplements at once?
Often yes, but check the labels for overlapping ingredients so you don't double up on the same vitamin. Tell your doctor about anything containing high-dose biotin before blood tests, since it can skew some results. If you're pregnant, nursing, on medication or managing a health condition, ask your doctor before starting any new supplement.
