Aging of the face and upper neck is a complex process characterized by loss of collagen and elastic fibers, resulting in clinical skin laxity. Noninvasive interventions such as monopolar capacitively coupled radiofrequency (MRF) have gained popularity, offering a safer and more convenient alternative to traditional surgical face lift. The latest MRF device features larger tips, vibration, cooling, and impedance matching.
We performed the first open-label clinical trial, measuring the efficacy, safety, and patient satisfaction of this device for noninvasive lifting and tightening of the face and upper neck.
Forty subjects 30 to 60 years of age with mild/moderate skin laxity of the face and upper neck were enrolled. After pretreatment with ketorolac 60 mg intramuscular injection, subjects underwent treatment with MRF. Follow-up evaluations were performed on Days 30, 60, and 180.
Our study demonstrated that the newest generation MRF produced statistically significant improvement in skin laxity 6 months post-treatment, especially in the jowls and melolabial folds. According to the Investigator Global Aesthetic Improvement Score, 73% of subjects had improvement at 6 months post-treatment. Subject satisfaction and improvement questionnaires supported these findings.
Our data coupled with the excellent adverse effect profile validates MRF as an attractive treatment modality for facial and upper neck skin laxity.
面部和颈部的衰老过程是一个复杂的过程，其特征是胶原蛋白和弹性纤维的丧失，导致临床皮肤松弛。非侵入性干预，如单极电容耦合射频（MRF），已经越来越受欢迎，为传统的面部提升手术提供了更安全、更方便的替代方案。最新的 MRF 设备具有更大的探头、振动、冷却和阻抗匹配功能。
我们进行了首次开放性临床试验，测量了这种设备对面部和颈部非侵入性提升和紧致的疗效、安全性和患者满意度。
40 名年龄在 30 岁至 60 岁之间、面部和颈部有轻度/中度皮肤松弛的受试者参加了这项研究。在肌内注射酮咯酸 60 毫克预处理后，受试者接受 MRF 治疗。在第 30、60 和 180 天进行随访评估。
我们的研究表明，新一代 MRF 在治疗后 6 个月对面部皮肤松弛具有统计学上的显著改善，尤其是在颏部和口角皱纹处。根据研究者的整体美学改善评分，73%的受试者在治疗后 6 个月有改善。受试者满意度和改善问卷支持了这些发现。
我们的数据结合出色的不良事件概况验证了 MRF 作为一种有吸引力的面部和颈部皮肤松弛治疗方法。
