Acne commonly occurs in the pediatric population, affecting more than 80% of adolescents. The pathophysiology underlying acne is complex, described by the contribution of four factors — sebaceous hyperplasia, changes in follicular growth and differentiation, interactions in the follicular environment by Propionibacterium acnes, and resultant immune and inflammatory responses. The mechanisms of action of the pharmacotherapies used to treat acne target these pathophysiologic characteristics. Topical and oral antibiotics play an important role, providing anti-inflammatory effects, in addition to antibacterial actions. Recently published data have demonstrated that antibiotics may be inappropriately relied upon when treating acne, with treatment durations often exceeding published recommendations.
