Acne is inflammatory dermatosis which has high prevalence among adolescents. Possible outcome of acne are acne scars which represent large esthetic problem for such patients. Acne scars result from disturbances in the complex mechanisms of wound healing which progresses through inflammation, granulation tissue formation and matrix remodeling. Scar formation is in relation with severity and duration of inflammation in acne lesions. According to the tissue response to inflammation, there are hypertrophic scars, keloids and atrophic scars. Atrophic scars have been classified into icepick, rolling and boxcar scars. There are many therapeutic methods available for the treatment of acne scarring, including resurfacing techniques, dermal fillers and different surgical methods. Treatment for atrophic scars include: chemical peeling, ablative and nonablative lasers, fractional photothermolysis, dermoabrasion, microdermoabrasion, dermal fillers and surgical methods including punch excision, punch elevation and subcision. Methods for hypertrophic scars and keloids include: intralesional steroid therapy, silicone gel, laser, cryotherapy and surgery. Choosing the adequate method depends on the scar type and its characteristics, but individual characteristics of a patient, advantages, limitations of each method and expectations of patients should also be considered. Current therapeutic methods may achieve significant improvement in scar appearance, but none of it can achieve complete resolution of a scar. Early and adequate acne treatment, which minimizes inflammation in acne lesion, is the best method for prevention and moderation of acne scars.
