Acne Scars: An Update on Management

ABSTRACT

Acne vulgaris is a troubling skin disease known to have both physiologic and psychological effects on patients. Acne scars, a frequent complication, can further impact patients' quality of life. Scars result from an impairment in the healing process. Acne scars can be categorized as follows atrophic scars (including ice pick, rolling, boxcar subtypes) and trophic (including hypertrophic and keloid scars), the latter being less common. Though various treatment approaches have been suggested, there is a lack of high-quality evidence on effective, type-specific acne scar approaches. Herein, we aim to review the current evidence for treating various acne scars.
