Practical evaluation and management of atrophic acne scars: tips for the general dermatologist

Douglas Fife, Douglas Fife

Abstract

Atrophic acne scarring is an unfortunate, permanent complication of acne vulgaris, which may be associated with significant psychological distress. General dermatologists are frequently presented with the challenge of evaluating and providing treatment recommendations to patients with acne scars. This article reviews a practical, step-by-step approach to evaluating the patient with atrophic acne scars. An algorithm for providing treatment options is presented, along with pitfalls to avoid. A few select procedures that may be incorporated into a general dermatology practice are reviewed in greater detail, including filler injections, skin needling, and the punch excision.

Photos before (A) and immediately after (B) injection with poly-L lactic acid demonstrating how volumetric filling of the mid-face can improve the appearance of acne scars accentuated by underlying soft tissue loss. Although this effect is temporary, it approximates what the patient will ultimately achieve with 2 to 4 sessions of treatment.
