A prospective, nonrandomized, open-label study, comparing the efficacy, safety, and tolerability of fractional CO₂ laser versus fractional microneedling radio frequency in acne scars

Both modalities are equally effective in the treatment of acne scars; however, fractional MNRF having lesser down time and Post inflammatory hyperpigmentation (PIH) among darker skin shades, with good patient satisfaction score, makes it an efficient and safer treatment option as compared to FCO₂.
