SKIN LIGHTENING COSMETIC COMPOSITIONS AND METHODS

摘要

A cosmetic composition for topical application to skin is provided. The cosmetic composition includes vitamin B3 compound, a ricinoleate compound and a dermatologically acceptable carrier. The vitamin B3 compound and the ricinoleate beneficially or even synergistically up-regulate proteasomal protease activity as evidenced by a higher observed net luminescence value relative to the calculated net luminescence value in B16 melanoma cells.
