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.
