Acne

Acne usually begins at puberty, and is the most common of skin afflictions. The range of acne lesions varies from blackheads and whiteheads, to raised pimples, to inflammatory deep, red, painful cysts and nodules. The latter can leave scarring. Acne involving the back, chest, and shoulders is often more difficult to treat than facial acne alone.

Adult acne usually occurs in women in their 30's, some of whom never had teenage acne. It is often more inflammatory, with tender red papules and deeper cysts on the face.

Treatment of teenage acne usually includes medications such as topical or oral antibiotics, special washes, topical retinoids, azalaic acid, benzoyl peroxide, and in severe cases oral retinoids. Treatments can be combined with special light and lasers in the office setting.
