Microneedling radiofrequency in cosmetic dermatology and aesthetics

Microneedling radiofrequency (MRF) has emerged as a novel technique in cosmetic and aesthetic dermatology, combining the benefits of microneedling with radiofrequency (RF). This procedure utilizes fine needles to create controlled micro-injuries in the dermis, stimulating collagen and elastin production. Concurrently, RF energy is delivered through these needles, heating the deeper skin layers to promote further collagen remodeling and tightening effects. The synergy between these two modalities not only improves skin texture and tone but also effectively addresses concerns such as acne scars, wrinkles, and skin laxity. In addition, the treatment is suitable for various skin types and conditions, including acne vulgaris, hyperhidrosis, striae distensae, cellulite, androgenic alopecia, melasma, and rosacea. A series of 3–5 sessions with 2–4 weeks interval is recommended to achieve optimal results. As MRF continues to gain interest in aesthetic practices, its integration with other treatments, such as platelet-rich plasma, stem cell products, and its derivatives, further enhances outcomes. Overall, MRF represents an innovation in cosmetic dermatology and aesthetics that can provide quite promising therapeutic results for various cases of cosmetic and aesthetic dermatology. However, further research is still needed to assess its effectiveness. This literature review aims to increase understanding of the application of MRF in cosmetic dermatology and aesthetics.
