Submental skin laxity (SSL), manifesting as sagging skin and double chin, can significantly affect patients' self-perception and social interactions. While surgical treatments exist, non-invasive methods are increasingly sought for their minimal recovery time. This study assesses the safety and effectiveness of a novel microwave-based device for treating SSL, aiming to provide long-term improvements in skin tightness and appearance.
Ten female patients with moderate to severe SSL underwent two treatments spaced 30 days apart using a 2.45 GHz non-invasive microwave device, with a specific handpiece. Treatment sessions lasted 10 min each, targeting the submental region. The Submental Skin Laxity Grade (SMSLG) was assessed before treatment and 12 weeks after the final session. Safety was monitored, and standardized photographs were taken for clinical evaluation.
All patients showed a significant reduction in SSL, with SMSLG scores improving from a mean of 3.6 at baseline to 2.3 after 12 weeks. No adverse effects were reported, and patients experienced minimal discomfort during and after the treatment sessions. Photographs revealed visible improvements in skin tone and tightness across all cases.
The microwave-based treatment demonstrated significant efficacy in reducing SSL and improving skin tone with minimal side effects, offering a promising alternative to surgical interventions. This non-invasive approach provides effective outcomes in fewer sessions and may represent a new standard for non-surgical skin tightening in aesthetic dermatology.
颏下皮肤松弛（SSL）表现为皮肤下垂和双下巴，会显著影响患者的自我认知和社交互动。虽然存在手术治疗方法，但由于恢复时间短，非侵入性方法越来越受到青睐。本研究评估一种新型微波设备治疗SSL的安全性和有效性，旨在长期改善皮肤紧致度和外观。
10名患有中度至重度SSL的女性患者使用特定手持件的2.45GHz非侵入性微波设备，间隔30天接受两次治疗。每次治疗持续10分钟，针对颏下区域。在治疗前和最后一次治疗后12周评估颏下皮肤松弛分级（SMSLG）。监测安全性，并拍摄标准化照片进行临床评估。
所有患者的SSL均显著降低，SMSLG评分从基线时的平均3.6分提高到12周后的2.3分。未报告不良反应，患者在治疗期间及之后经历的不适最小。照片显示所有病例的肤色和紧致度均有明显改善。
基于微波的治疗在减少SSL和改善肤色方面显示出显著疗效，且副作用最小，为手术干预提供了一种有前景的替代方法。这种非侵入性方法在较少的治疗次数中即可提供有效结果，可能代表了美容皮肤科非手术皮肤紧致的新标准。
