Abstract  Background: Acne scarring has lifelong sequelae and are extremely disturbing to patients, both physically and psychologically. The use of ablative fractional lasers for the treatment of acne scars is becoming increasingly popular. But studies regarding the efficacy and safety of the same in the Indian skin is limited. Objective: To evaluate the efficacy and safety of Erbium-doped Yttrium Aluminium Garnet (Er: YAG) 2940 nm fractional laser resurfacing in the treatment of acne scars in 10 patients at a tertiary care teaching hospital Methodology: All 10 patients received four treatment sessions with Er: YAG fractional laser at 1-month interval. Subjective assessment in percentage of improvement was documented after four sessions. Subjects were instructed to report any cutaneous side-effects including erythema, oozing, crusting, dyschromia, scarring or secondary infection and about interference with daily activities in the post-treatment period. Photographs were taken before each treatment session and 1 month after the final session. A clinical assessment by comparing the photographs was done. Patient's satisfaction of improvement was noted at the end of four sessions. Conclusion: Er- YAG laser resurfacing is both effective and safe in the treatment for acne scars.
