Acne affects the areas of the skin that contain sebaceous glands, including the face, upper chest, and back. Acne occurs most commonly during adolescence. Many new treatment regimens are available for acne, especially for the most severe types. Permanent scarring may follow a severe case of acne. Men are more often affected on their shoulders and back than are women.
Cystic acne is a severe form of acne that can cause pitting and scarring.
There are several large cysts on the cheek and forehead, with many smaller pustules. Preventing new lesions and limiting the amount of scarring are the primary goals of treatment. Because of the deeper inflammation the tendency for scarring is increased. Acne lesions frequently contain pus. If the rosacea continues to the fourth stage, it is called rhinophyma.
