Abstract

Objective: To compare the efficacy of MNRF and Fractional CO2laser in patients with atrophic acne scars.
Materials and methods: This study is prospective randomized, comparative study done after obtaining the patient’s consent. 40 patients with atrophic acne scars in the age group 18 years to 35 years were included in our study. They are divided into Group A and Group B with 20 patients each. MNRF was done for Group A and Fractional CO2 laser was done for group B. Both groups were treated for 4 sessions at 4 weekly intervals.
Results: In our study, the maximum number of patients were under the age group of 22-25 years. Males (72.5%) were more commonly affected than females (27.5%).45% had scars for a period of 1-3 years. The most common type of acne scar is the mixed/combined type (50%). Majority of the patients in MNRF had Grade 3 acne scars (40%) and fractional co2 had Grade 2 acne scars (60%). The common complications observed in our study was erythema (45%).
Conclusion: Micro-Needling Radiofrequency was found to be safest and more effective modality when compared with fractional co2 laser for the treatment of atrophic acne scar.
