Abstract
Acne, the most prevalent disease of the skin, is a multifactorial follicular disorder in which androgens and microbiology are essential for the occurrence of the pathogenic events that characterize it. The role of the androgen is to stimulate the development and secretory activity of the sebaceous gland, which performs several important actions in the etiopathogenesis of acne. The anaerobic diphtheroid Propionibacterium acnes, a resident organism in acne‐susceptible follicles, is directly responsible for much of the inflammation in acne. This review deals with a description of these events and the therapeutic modalities that have been developed in an attempt to counteract them.
