The aetiopathogenesis of acne vulgaris - What's new?

Abstract

Synopsis Acne vulgaris is the most frequently diagnosed dermatosis in patients between 11 and 30. It is believed that it affects about 80% of persons in this age group or even, taking into account lesions of low intensity, 100% of young people. The aetiopathogenesis of acne is multifactorial. In all patients with acne, the following symptoms occur: excessive sebum production, excessive keratosis of excretory ducts and openings of sebaceous glands, development of bacterial flora and release of inflammatory mediators in the skin. Development of molecular biology, genetics and immunology contributed to a significant progress in studies on the pathogenesis of acne. © 2014 Society of Cosmetic Scientists and the Société Française de Cosmétologie.
