Management of acne vulgaris.

Acne is a chronic and multifactorial skin condition affecting about 80% of persons aged 11 to 30 years, the majority of whom are adolescents (Morelli, 2007, Shamban and Narurkar, 2009, Zaenglein and Thiboutot, 2006). Although acne has no cure and has the potential to cause emotional distress and permanent scarring, proper treatment can control the disease and greatly limit the morbidity. In recent years, acne treatment guidelines have been revised based on a better understanding of acne pathophysiology, and they currently aim to target as many pathogenetic factors as possible. This practice guideline will highlight the most recent treatment guidelines for adolescent acne.
