- OBJECTIVES: Atrophic post-acne scarring remains a therapeutically challenging condition despite various currently available technologies. Fractional photothermolysis (FP) is a novel concept of cutaneous resurfacing which induces non-contiguous microscopic thermal injury. The aim of this study is to evaluate the safety and efficacy of FP in the treatment of acne scars in Asian patients. METHODS: A total of 27 Korean patients (Fitzpatrick skin types IV or V) with moderate to severe facial acne scars received three to five sessions of FP treatment (Fraxel Laser; Reliant Technologies, CA, USA), each spaced 3-4 weeks apart. Standardized digital photographs were obtained before each treatment and 3 months after the final treatment. In addition, the patients' perceived degrees of improvement were assessed 3 months after the final treatment using a five-point grading scale. RESULTS: FP led to marked improvement in the appearance of acne scars at 3 months post-treatment. Patients' self-assessed degrees of improvement were as follows: excellent improvement in eight patients (30%), significant improvement in 16 patients (59%), and moderate improvement in three patients (11%). Adverse events were limited to transient pain, erythema and edema. CONCLUSIONS: The 1550-nm erbium-doped FP is associated with significant patient-reported improvement in the appearance of acne scars, with minimal downtime.
