Benefits of anti-aging actives in sunscreens

Abstract

Sunscreens are functional, utilitarian, cosmetic products. The criteria of purchase are different from those for skin care and make-up. Companies are trying to add glamour and value to basic sunscreens by incorporating "active" ingredients (other than UV filters) into these formulas and by communicating about the additional benefits, be they anti-aging, moisturizing, firming, anti-wrinkle, etc. While some of these ideas of additional ingredients make sense as supplementary skin protection, some others do not afford much benefit in view of the infrequent application and short period of usage. The present article reviews some of these ideas and presents a few active ingredients that might be of value in such a context, even if substantiation of such additional claims in sunscreens is often lacking.
