TOPICAL COMPOSITIONS
A method of reducing oxidative damage of skin is disclosed. The method includes applying to oxidant damaged skin a topical composition comprising oligopeptide-1 and niacinamide, wherein the combination of oligopeptide-1 and niacinamide reduces oxidative damage in the skin, and wherein the oligopeptide-1 includes the sequence of caprooyl-Gly-His-Lys-Lys.
