This study was performed to determine the effectiveness and safety of fractional CO₂ laser therapy in the treatment of acne scar. A prospective clinical trial was done in the Department of Dermatology and Venereology, Bangabandhu Sheikh Mujib Medical University (BSMMU) and Combined Military Hospital (CMH), Dhaka, to find out the efficacy and safety of fractional CO2laser in the treatment of acne scars. A total of 60 patients with moderate to severe acne scars were treated with Fractional CO2 laser therapy at baseline and after 4, 8, 12,20, and 28 weeks. It was found that among the 60 patients included in the study, the majority was below the age of 30 years and female. The acne scar was significantly reduced after 4, 8, 12, 20, and 28 weeks of treatment with Fractional CO2 laser therapy. The level of improvement observed varied from excellent to poor, with the majority of patients experiencing fair to excellent improvement. The majority of patients tolerated the treatment with negligible adverse effects. It can be concluded that Fractional CO2 laser is highly effective and well tolerated by patients in the treatment of acne scars.
