Acne vulgaris is American's most common disease and is characterized by noninflammatory, open or closed comedones and by inflammatory papules, pustules, and nodules [James Fulton Jr, eMedicine]
Acne vulgaris 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. [James Fulton Jr, eMedicine]
The pathogenesis of acne vulgaris is multifactorial. The key factor is genetics (propensity for follicular epidermal hyperproliferation with subsequent plugging of the follicle).Additional aggravating factors include excess sebum, the presence and activity of Propionibacterium acnes, and inflammation [James Fulton Jr, eMedicine]
