A split‐face comparison of a fractional microneedle radiofrequency device and fractional radiofrequency therapy for moderate‐to‐severe acne vulgaris

Abstract

Fractional microneedle radiofrequency is faster and more effective than FR for the treatment of moderate and severe acne after only one treatment. However, after several treatment sessions, both FMR and FR proved to be safe and effective for long-term treatment of moderate-to-severe acne. Therefore, invasive radiofrequency, such as FMR, or noninvasive radiofrequency, such as FR, can successfully treat active acne.
