Vitamin E is the name of the tocopherol family. In cosmetics, either free tocopherol, which is fragile, or its ester, tocopheryl acetate, which is more stable, is used6. It is the main lipophilic antioxidant of the stratum corneum, which is depleted by UV8. Trials mostly test the combination with vitamin C, at 1% vitamin E910.

Each result shows the protocol and the level of evidence. The higher the level, the better the result carries over to a finished formula.
The vitamin E level is more than ten times lower at the surface than deep in the stratum corneum (6.5 versus 76 pmol/mg for α-tocopherol). A sun dose below the redness threshold lowers it by 45% (α) and 35% (γ)8.
Skin tone, elasticity and radiance improved, with less scaling and fewer wrinkles than the untreated side. Tingling and a tight feeling were reported. Vitamin E is not tested alone12.
Photoprotection is significant on all the criteria assessed: erythema, sunburn cells, thymine dimers, p53 and cytokines. The sample was small; this is not a substitute for sunscreen10.
The combination protects better against erythema and sunburn cells than either vitamin alone, with an antioxidant protection factor of 4. Each vitamin alone already protects9.
In the combination, most of the protection against UVB comes from vitamin E. Vitamin C protects better against the effects of UVA, and adding a UVA filter gives more than additive protection against phototoxic damage11.
The acetate is not converted at the surface or in the stratum corneum. In the underlying skin, up to 50% of the total is deacetylated. The dosage form changes deposition: acetate in oil stays at the surface and in the stratum corneum6.
α-Tocopherol and ascorbic acid have excellent antioxidant power, the acetate better than average. The authors suggest that the acetate converts to α-tocopherol in the stratum corneum in less than 2 weeks7.
The authors report photoprotective and barrier-stabilizing properties in experimental studies, but stress the lack of controlled trials to set doses5.
The panel concludes that these ingredients are safe as used in cosmetics. The 2002 report had already assessed tocopherol and its esters, including the acetate34.
0.9% positive tests (349 people), most often to skincare products, especially moisturizers. The authors consider this rate low given the very widespread use13.
This page summarizes published literature on a cosmetic ingredient. It does not describe the effect of a finished product, which depends on its formula, and it is not medical advice. Vitamin E is most often tested with vitamin C: the effect of vitamin E on its own is not always isolated. Several photoprotection studies use animal models, which is stated.
The trials cited test vitamin E at 0.5 and 1%, in combination with vitamin C for photoprotection. These studies do not establish a dose for the acetate alone: the final concentration is set with the formulator, depending on the role you want (formula antioxidant or skincare antioxidant).
Our white label catalog includes 117 formulas with vitamin E: the key active in 4 of them, a supporting ingredient in the others. Every category can be customized (formula, fragrance, packaging).
Key active in the vitamin C and E antioxidant serum, supporting antioxidant in oils, masks and creams.
Antioxidant for the oil phases of lotions, butters, balms, scrubs and sun care.
Supporting antioxidant in oils, serums, masks and leave-ins.
In our formulas, it is most often paired with
Argan oil 45Panthenol 38Sweet almond oil 31Coconut oil 29Shea butter 26The four actives that come up in an antioxidant formula. Photoprotection trials combine vitamins C and E910.
