ABSTRACT

Ablative laser resurfacing is an effective treatment for acne scars. However, edema and prolonged erythema are common. Additionally, scarring and hyperpigmentation are often induced. A new concept of laser called fractional photothermolysis has been designed to create microscopic thermal wounds to achieve skin rejuvenation without significant side-effects. We treated 10 patients with acne scars using this laser system (Reliant Fraxel SR Laser). All the patients were successfully treated with minimal adverse effects. The fractional photothermolysis system represents an optional method for the treatment of acne scars.
