Comparison of Fractional Micro‐Plasma Radiofrequency and Fractional Microneedle Radiofrequency for the Treatment of Atrophic Acne Scars: A Pilot Randomized Split‐Face Clinical Study in China

Both fractional micro-plasma RF and fractional microneedle RF are effective and safe methods for improving atrophic acne scars. Fractional micro-plasma RF is significantly more effective for atrophic acne scars, especially for rolling scars. However, fractional microneedle RF has fewer side effects plus shorter downtime, and patients are more comfortable after the treatment. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.
