Popis:	SummaryBackground The 1550 nm Er:Glass fractional laser is widely used for the treatment of atrophic acne scar. A novel fractional radiofrequency microneedle device has recently emerged as an alternative for treating acne scars. Objectives To evaluate the clinical efficacy and safety of a Er:Glass fractional laser and fractional radiofrequency microneedle device in the treatment of facial atrophic acne scars and to assess the difference between the treatment modalities depending on facial compartment. Methods A total of 40 patients were equally randomized into two groups. Each group of 20 patients received three treatments at 4-week interval using Er:Glass fractional laser or fractional radiofrequency microneedle device. Results Scar severity scores (ECCA grading scale) improved by a mean of 25.0% and 18.6% in groups A and B, respectively (both P
