The role of cosmetics in postadolescent acne

The role of cosmetics in the induction and perpetuation of adult acne has been debated. This study reports the effects of a cosmetic regimen consisting of six formulations of low predicted acnegenic potential on the course of mild postadolescent acne in ten young women. No increase in activity of disease as measured by comedo and inflammatory papule counts was noted in these subjects; on the contrary, a decreasing trend in the total number of comedones and papules was noted throughout the cosmetic use period of the study. The premarketing "in-use" testing of cosmetic formulations intended for use by the postadolescent consumer with mild acne is suggested.
