This type of acne is a unique type of acne where the face becomes studded with whiteheads. This process is called maturation arrest acne because the comedones do not go ahead and mature into actual blackheads. The whiteheads just continue to get larger. The surface opening never dilates, leaving the dead skin cells or keratinocytes to become trapped inside. Because this is one of the toughest acne to treat, suggested treatment is a series of peels to force the impactions to open up.
