Scars are the most feared complication of pimples. It is impossible to predict who will develop scars, and scarring is not always coincide with the severity of acne. It is believed that eleven percent of men and 14 percent of women with pimples develop scars. Some studies have shown an even higher rate.
Scars from acne can have many different forms, and it is significant for any treatment. Treatment of scars are generally difficult, and one must have realistic expectations.
Pimple scars can be raised from the surface of the skin (hypertrophic / keloid) or seen as depressions in the skin (atrophic). Raised scars can be done better in some people by injecting cortisone. Small depressions in the skin ("ice-pick scars") can be removed surgically. Light scarring can also be improved with the use of chemical peeling.
