Abstract
The invention provides antioxidant-containing compositions and methods for confirming antioxidant activity of a composition formulated for topical application to skin. The invention also provides methods for testing a composition for the ability to inhibit both ultraviolet radiation-induced lipid peroxidation on skin and ultraviolet radiation-induced reactive oxygen species formation in the stratum corneum as well as compositions and methods for treating and preventing photodamage to skin.
