Various radiofrequency (RF) devices are used to treat skin laxity and face contouring, but few studies have examined ultrahigh-frequency (UHF) electric field (40.68 MHz) RF devices.
To evaluate the efficacy and safety of a UHF electric field (40.68 MHz) RF device for skin tightening and face contouring.
Ten patients each underwent four sessions of UHF electric field RF device treatment at 2-week intervals. Clinical improvement was evaluated with the patient satisfaction score using a six-point scale, and clinical photographs taken at every visit and 2 months after the RF treatment were assessed. Skin biopsies were obtained from one patient before the first treatment and immediately after the last treatment. Adverse reactions were recorded at every follow-up visit.
All patients were women with a mean age of 51.7 ± 7.2 years. The mean satisfaction score was 4.5 ± 0.9 immediately after the last treatment session. Cheek, jawline, and neck enhancement and tightening were apparent in all patients. Side effects were minimal, and there were no burns or major complications.
The UHF electric field RF device was effective for skin tightening and facial contouring, without significant adverse reactions.
各种射频(RF)设备用于治疗皮肤松弛和面部轮廓塑造,但很少有研究考察过超高频(UHF)电场(40.68兆赫)射频设备。
评估超高频电场(40.68兆赫)射频设备用于皮肤紧致和面部轮廓塑造的疗效和安全性。
10名患者每隔2周接受4次超高频电场射频设备治疗。使用六点量表通过患者满意度评分评估临床改善情况,并对每次就诊时以及射频治疗后2个月拍摄的临床照片进行评估。在1名患者首次治疗前和最后一次治疗后立即进行皮肤活检。每次随访时记录不良反应。
所有患者均为女性,平均年龄51.7±7.2岁。最后一次治疗后立即的平均满意度评分为4.5±0.9。所有患者的脸颊、下颌缘和颈部均有明显的提升和紧致效果。副作用极小,未出现烧伤或严重并发症。
超高频电场射频设备对皮肤紧致和面部轮廓塑造有效,且无明显不良反应。
