Acne Scarring

One of the most common inflammatory skin diseases encountered by dermatology practitioners is acne. Onset of acne typically occurs at age of puberty, affecting 95% to 100% of adolescent boys and 83% to 85% of adolescent girls; in 12% to 14% of cases, acne persists into adulthood. Acne scarring affects up to 95% of patients with acne and is categorized as severe in 30% of patients. This scarring is one of the most emotionally distressing and long-term consequences of acne—not only do patients find it aesthetically displeasing, but it also confers a significant social and emotional burden.

Acne scar development is attributed to cutaneous inflammation catalyzing an altered wound healing response. The result is an excess of collagen deposition that presents as hypertrophic scars or, in 80% to 90% of cases, decreased collagen deposition that presents as atrophic acne scars. These atrophic scars can be categorized into 3 basic types: icepick, rolling, and boxcar, with the icepick type being the most common presentation (60%-70%).

Treatment options for acne scars include surgical (eg, excision, subexcision, punch techniques) and nonsurgical (eg, dermabrasion, needling, chemical peels, injectable fillers, energy-based devices) approaches. Each individual scar may require a different treatment approach based on characteristics such as color, depth, and morphology. As such, a combined approach may be warranted for optimal results. Recently, for the first time, plastic surgeons and dermatologists from multiple countries collaborated to provide a consensus for treatment of acne scars, with a focus on energy-based devices. This consensus was published in Lasers in Surgery and Medicine; it has so much good information for a problem that has been difficult to treat for many years.
