Fractional CO2 Laser and Chemical Peeling for Treatment of Acne and Acne Scars: A Comparative Study

Abstract

Background: Acne is a common disorder with a more prevalence among adolescents and often it causes atrophic scars. Several treatment options are available for acne and atrophic acne scars treatment. The objective of the study was to compare the efficiency of fractional CO 2 laser and chemical peeling versus chemical peeling alone in treatment of acne and acne scars. Methods: Thirty-two patients with acne and acne scars were enrolled in the study. procedure was done to all patients and repeated at every two weeks intervals for atotal of 4 sessions. Patients were followed up 4 weeks after the last session. The response to treatment was assessed by objective and subjective methods. Results: All patients completed the study and follow up period. There was statistically significant improvement in the scar depth in the left sides of faces of both acne scars subgroups. The first acne subgroup showed statistically significant improvement in the left sides, while the improvement in the left sides of the second subgroup was statistically insignificant. Conclusion: Both fractional CO 2 laser and SA high concentration gave equally effective results in treatment of acne vulgaris .. Yet, fractional CO 2 laser is superior to mandelic acid chemical peeling in treatment of post acne scars even in high concentration.
