Efficacy and safety of ablative fractional carbon dioxide laser for acne scars
Keywords:
Acne scars, fractional CO2laserAbstract
Background Acne may lead to long term squelae including physical scars. Lasers have been used with variable degree of success but literature pertaining to  Asian population is sparse. Objectives To evaluate the efficacy and safety of carbon dioxide (CO2) fractional laser in the treatment of acne scars in the local population. Patients and methods Twenty patients with mild to moderate atrophic acne scars were registered and subjected to monthly fractional CO2 laser resurfacing for six sessions and final evaluation was done six months after the last treatment. Results More than 71% patients showed variable degree of improvement. No severe long term complications were noted in any patient. Conclusion Study suggests that CO2 Fractional laser may prove a useful addition in the management of acne scars in our patients as well.ÂReferences
