Fractional Microneedle Radiofrequency: Mechanism of Action and Assessment of Safety, Effectiveness in Treatment, and Possible Side Effects Based on a Review of Scientific Literature

Fractional microneedle radiofrequency (FMR) is a minimally invasive aesthetic procedure that combines microneedling with radiofrequency to induce neocollagenesis, neoelastinogenesis, and angiogenesis in the skin. This technique, which can penetrate up to 4.5 mm into the skin, is used for skin rejuvenation, skin tightening, scar remodeling, and promoting hair growth. The review of scientific literature suggests that FMR is effective and safe, with a minimal risk of serious side effects, making it an appealing option for patients seeking less invasive skin treatments. However, the document indicates that more research is necessary to fine-tune the treatment parameters for optimal results.
