Facial photoaging has become a major cosmetic concern, and the microneedle fractional radiofrequency system (MFRS) is a novel method for rejuvenation that combines radiofrequency and microneedles.
This study prospectively evaluated the efficacy and safety of an MFRS in the treatment of facial photoaged skin in Chinese patients.
Twenty-seven patients with moderate facial photoaging were recruited and received 3 treatments at 4-week intervals. Blinded clinical assessment was performed by 2 independent dermatologists on a 5-point global photoaging scale (GPS). Patients were also questioned on the extent of improvement of rhytides, skin tightening, and complexion with a 4-point global aesthetic improvement scale (GAIS) and satisfaction based on a 5-point scale. Adverse events and pain scores were also evaluated.
Compared with the baseline, there was a significant improvement in facial photoaged skin after 3 treatments, and these positive outcomes were maintained up to the 6-month follow-up, according to the GPS and GAIS scores. Most patients were satisfied with the treatment and reported mild to moderate pain and adverse effects.
This MFRS is effective for facial skin rejuvenation in Chinese patients. The therapy also seems safe and well tolerated.
面部光老化已成为美容的主要关注点，微针分段射频系统（MFRS）是一种结合射频和微针的新型皮肤年轻化方法。
本研究前瞻性评估 MFRS 治疗中国患者面部光老化皮肤的疗效和安全性。
招募了 27 名中度面部光老化患者，每 4 周接受 3 次治疗。2 名独立皮肤科医生采用 5 分制全球光老化量表（GPS）对患者进行盲法临床评估。患者还根据 4 分制整体美学改善量表（GAIS）和 5 分制满意度对皱纹改善程度、皮肤紧致度和肤色进行了评估。还评估了不良反应和疼痛评分。
根据 GPS 和 GAIS 评分，与基线相比，经过 3 次治疗后，面部光老化皮肤有显著改善，这些积极的结果一直持续到 6 个月的随访。大多数患者对治疗满意，并报告轻度至中度疼痛和不良反应。
MFRS 对中国患者的面部皮肤年轻化有效。该疗法似乎安全且耐受性良好。
