ABSTRACT: The use of topical antioxidants is gaining favor among dermatologists because of their broad biologic activity. Many are not only antioxidants but also have antiinflammatory and anticarcinogenic activities. Thus for dermatologists these cosmeceuticals have many potential applications. In general, topical antioxidants exert their effects by down-regulating free radical mediated pathways that damage skin. The present study will describe the science behind some of the newest topical antioxidants and outline how they can be used as part of a comprehensive skin care regimen.
