[Acne vulgaris. Role of cosmetics].

Appropriate cosmetics for skin cleansing are capable of contributing to a reduction of especially inflammatory lesions in acne-prone patients and to support pharmacological intervention in patients with manifest acne. Cleansing of acne-prone skin should employ acidified synthetic cleansers with a pH of 5.5 rather than soap. Furthermore, the ingredients of certain skin care products, i.e. nicotinamide, lactic acid, triethyl acetate/ethyllineolate, and prebiotic plant extracts, affect different mechanisms of acne pathogenesis and therefore may contribute to a decrease in acne lesions. At least some of these ingredients underscore the concept of evidence-based cosmetics. In contrast, the problem of acne lesions caused by comedogenic ingredients in cosmetics today is negligible.
