Background: Many interventions have been used to treat post-acne scars, with various degrees of efficacy and adverse reactions. Multimodal approach can achieve better results for improving the physical appearance that even if minor may result in significant distress and reduced quality of life.

Objective: To compare the efficacy of subcision with fractional carbon dioxide (CO2) laser and subcision with microneedling fractional radiofrequency (RF) in treating post-acne scars and to study their adverse effects.

Methods: In this prospective, interventional clinical study, a total of 64 patients with post-acne scars were enrolled. The patients were randomly allocated into two groups of 32 patients each, in which group A was treated with subcision plus fractional carbon dioxide laser (CO2) and group B was treated with subcision plus microneedling fractional radiofrequency (RF) every 6 weeks for a total of four sittings. An objective score was calculated for each patient using the Goodman and Baron scale to evaluate the outcome every visit during treatment and then 3 months after completion of therapy.

Results: In group A, the percentage reduction in the mean objective scores was found to be 64%. In group B, the percentage reduction in mean objective scores was found to be 42%. Most of the changes were seen in the boxcar and rolling types of scars.

Conclusions: Subcision and fractional CO2 laser were considered superior over subcision with microneedling fractional (RF) technique for the treatment of post-acne scars. Boxcar and rolling types of scars showed a high response to treatment than icepick scars
