Objective To investigate the efficacy and safety of uhrapulsed fractional CO2 laser in the treatment of scar. Methods 58 patients with scar, including 32 acne scar, 11 traumatic scar,8 burn scar and 7 suture scar, were treated with ultrapulsed fractional CO2 laser once every 3 months. Digital photos were taken before and after the treatment. The efficacy and the side effects were evaluated 1 month and 3 months after the treat- ment.
