Acne vulgaris is characterized by noninflammatory, open or closed comedones and by inflammatory papules, pustules, and nodules. Acne vulgaris typically affects the areas of skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back.
Acne vulgaris is the most common skin disease in the United States. It affects an estimated 80% of Americans at some time during their lives. Twenty percent have severe acne, which can result in permanent physical and mental scarring.
