Acne Scar Treatment

Abstract

Acne is a chronic infl ammatory disease of the pilosebaceous follicles characteristically but not exclusively affecting adolescents, having a 35-90 % prevalence in young people between the ages of 14 and 19, generally resolving spontaneously after age 20 in men and age 25 in women. However, in some cases, usually in women, acne can persist through adulthood. The occurrence of scars, more or less pronounced, in patients with previous acne is >80 % of patients. About 5 % of patients present with a severe form of acne, and especially in these cases, acne can result in permanent scars that can be highly disfi guring and conditioning for the patient, causing serious social discomfort and decreased self-esteem. Typology of ScarsAcne scars can be atrophic, hypertrophic, or keloid. They can vary in shape, depth, and dimension and often coexist in the same patient. The scars also can be associated with skin discoloration (hypo-or hyperpigmentation).
