SBC Medical Group Holdings (location: California, USA, CEO: Yoshikazu Aikawa) announced that a paper co-authored by Dr. Ayaka Nishikawa, who serves as the General Director of Dermatology at Shonan Beauty Clinic, which receives management support from the group, has been published in the international academic journal for aesthetic and reconstructive plastic surgery, "Aesthetic Plastic Surgery" (published by Springer, official journal of the International Society of Aesthetic Plastic Surgery). The paper, titled "Effectiveness of Radiofrequency Microneedling in the Treatment of Dermatological Conditions: A Systematic Review," comprehensively analyzes the effectiveness and safety of "Radiofrequency Microneedling (RFMN)," a cosmetic medical technology that has recently garnered attention, based on clinical studies from around the world. It demonstrated the potential for RFMN as an effective treatment for various skin concerns, including acne scars, skin sagging, and wrinkles.
Radiofrequency Microneedling (RFMN) is a treatment that combines微針 with high-frequency energy to stimulate collagen production deep within the skin. It is gaining popularity both domestically and internationally as a procedure that can improve skin quality while minimizing downtime. However, previous research was fragmented by disease, and comprehensive data evaluating its efficacy across a wide range of symptoms was limited.
In this study, the effects and safety of RFMN were comprehensively evaluated based on multiple clinical studies published over the past decade. The results confirmed an improvement effect on acne scars equivalent to conventional treatments, while also demonstrating its utility in terms of faster recovery and fewer side effects. Furthermore, improvements in skin sagging and wrinkles were also confirmed, suggesting a broad range of indications. Regarding safety, temporary redness was the primary mild reaction, with no serious complications reported, and satisfaction levels were shown to be high.
In recent years, technological innovation has advanced in the field of aesthetic medicine, increasing the importance of sharing specialized knowledge and academic collaboration not only in clinical practice. To meet diverse needs, it is essential to introduce cutting-edge technologies with a broad perspective and flexible ideas. SBC Medical Group will continue to promote advanced initiatives through academic activities and exchanges with research institutions, striving to improve the safety, transparency, and sustainable value of cosmetic medicine.
