Vitamin E (Tocopherol)
Lipid-soluble antioxidant and formula stabiliser
Function in skin biology
Vitamin E (tocopherol, in its various isomeric forms) is a lipid-soluble antioxidant naturally present in skin's sebum. In cosmetic formulation, it is evaluated for its antioxidant capacity — helping protect formula oils and other actives from oxidation — and for its own contribution to skin surface comfort as an emollient-adjacent ingredient.
Why Ambernay evaluates it
Vitamin E is commonly included in Ambernay's formulation evaluation for two roles simultaneously: as a finished-product antioxidant (helping protect formula stability over shelf life) and as a complementary antioxidant alongside other actives such as vitamin C, where the two are frequently studied together for extended antioxidant stability.
Where concentration matters
Vitamin E is typically formulated at 0.5–1% in cosmetic products, both for its own contribution and its formula-stabilising role. Higher concentrations are not necessarily more effective and can affect formula texture.
What we do not claim
We do not claim that vitamin E heals scars, treats stretch marks or repairs structural skin damage — claims commonly seen in vitamin E marketing that are not supported by the cosmetic evidence base. Vitamin E in a cosmetic formula is evaluated as an antioxidant and stabiliser.
Best paired with
Vitamin E is frequently formulated alongside vitamin C and ferulic acid for combined antioxidant stability, and is compatible with most other actives in this guide.
Claim caution / regulatory note
Vitamin E is a cosmetic antioxidant ingredient. Claims must remain within cosmetic function: antioxidant support, formula stability, skin feel. Scar treatment, wound healing or structural repair claims are not permitted in a cosmetic context and are not supported by the available evidence for topical tocopherol.
