Vitamin E, also known as tocopherol, is a widely used liposoluble antioxidant in cosmetics. It exists in several forms, with alpha-tocopherol being the most studied. Available scientific data associate it with several properties of cosmetic interest.
Antioxidant activity: vitamin E is associated, according to available data, with protection against oxidative stress caused by UV and pollution, one of the factors contributing to visible signs of aging. Its liposoluble nature allows it to position itself in the lipid cell membranes, where it helps protect against free radicals generated in the skin's fatty structures.
Hydration comfort and suppleness: vitamin E is linked to supporting skin comfort and visible skin suppleness. It is documented for its emollient properties that contribute to softer, more comfortable-looking skin.
Documented soothing properties: vitamin E is associated, according to available data, with visible reduction of redness and discomfort sensations, for the comfort of sensitive or reactive skin.
Support for skin appearance over time: vitamin E is linked to visible reduction of time-related marks and supporting skin appearance after environmental exposure. It complements appropriate sun protection and does not replace it.
Formulation note: vitamin E is also used as a formulation antioxidant to protect other actives from oxidation, a documented role distinct from its cosmetic action on the skin.
In summary, a versatile liposoluble antioxidant documented for protection against oxidative stress, skin comfort, and soothing properties.
