Also known as: Tocopherol, Alpha-Tocopherol, Tocopheryl Acetate
Tocopherol (vitamin E) is a fat-soluble antioxidant that protects cell membranes from oxidative damage. In skincare it is used to stabilise formulations (particularly oils prone to oxidation) and provides antioxidant protection to the skin. Works synergistically with vitamin C. At higher concentrations it can be comedogenic for some skin types. The most commonly used form is alpha-tocopherol.
Comedogenicity ratings are based on the rabbit ear assay model. Individual skin responses vary. See our article on comedogenicity ratings for context.
