Acne vulgaris (AV) is a chronic inflammatory disease affecting the pilosebaceous apparatus. Clinically, it is characterized by two main categories of lesions: non-inflammatory (closed and open comedones) and inflammatory (papules, pustules, nodules, and cysts). Physical and psychological problems are often encountered in acne patients, with post acne scars being the most disfiguring sequelae. Scarring is a consequence of abnormal healing following damage to the sebaceous follicle during acne inflammation. Acne scars are classified into atrophic and hypertrophic types. Atrophic scars are further subdivided into rolling, icepick, and boxcar subtypes. Several modalities are used for these scars, including chemical peeling, dermabrasion, microneedling, platelet-rich plasma (PRP), laser resurfacing, subcision, and punch elevation technique. Atrophic post-acne scars present as depressions secondary to fibrous contractions. They are classified into three types: boxcar, icepick, and rolling scars. Boxcar scars are round to oval depressions with sharply demarcated vertical edges and a flat bottom. Icepick scars are deep and narrow, sharply demarcated tracts that extend to the deep dermis. Rolling scars are wide, shallow, or deep depressions with gently sloped edges. Acne scar treatment has traditionally used a variety of techniques, and innovative modalities are always being developed to achieve the best outcomes.
