Abstract

Background

The aging process reflects decreased tissue elasticity and a rearrangement of subcutaneous volume, resulting in superficial wrinkles and three-dimensional changes in skin topography. Radiofrequency (RF)-based approaches have become increasingly adopted in recent decades due to their relatively short downtime and significantly reduced risk of adverse effects.

Aims

The aim of this study was to evaluate the safety and efficacy of the V-FC handpiece through a multicenter retrospective study as well as ex vivo and in vivo analyses.

Methods

The V-FC handpiece was used once a week for a treatment course of 3–6 sessions. The clinical evaluation of 33 patients included demographics, BMI, assessment of skin laxity, and rate of improvement. An ex vivo study with porcine tissue assessed the penetration depth of RF, while device performance was evaluated in an in vivo animal histological analysis.

Results

No significant adverse effects were recorded during the treatment course or at short- and long-term follow-ups (1, 3, and 52 months). The average skin laxity grade baseline was 34% lower at the end of the treatment course, with the average rate of improvement assessed as moderate. The ex vivo minimal and maximal penetration depths were 3.2–11.3 mm (±10%). The in vivo histopathological analysis showed no signs of acute heat injury at any treatment setting, including the maximum RF power. Additionally, staining showed a power-related progressive proliferation of fibroblasts, elastin fibers, and neocollagenesis, which was significantly higher 4 weeks after treatment.

Conclusions

The new RF device demonstrates an effective treatment for facial contouring with a proven short- and long-term high safety profile.

背景老化过程反映了组织弹性的降低和皮下容积的重新排列，从而导致表皮皱纹和皮肤地形的三维变化。近几十年来，基于射频（RF）的方法因其停工期相对较短且不良反应风险显著降低而被越来越多地采用。目的本研究旨在通过一项多中心回顾性研究以及体内外分析，评估 V-FC 手机的安全性和有效性。方法 V-FC 手机每周使用一次，疗程为 3-6 次。对 33 名患者进行的临床评估包括人口统计学、体重指数、皮肤松弛评估和改善率。一项使用猪组织进行的体外研究评估了射频的穿透深度，而设备性能则通过体内动物组织学分析进行了评估。结果在治疗过程中以及短期和长期随访（1 个月、3 个月和 52 个月）中，均未发现明显的不良反应。在疗程结束时，基线皮肤松弛等级平均降低了 34%，平均改善率被评为中等。体内最小和最大渗透深度为 3.2-11.3 毫米（±10%）。体内组织病理学分析表明，在任何治疗设置（包括最大射频功率）下，都没有急性热损伤的迹象。此外，染色显示成纤维细胞、弹性纤维和新胶原的增殖与功率有关，在治疗 4 周后明显增加。结论新型射频设备是面部塑形的有效治疗方法，其短期和长期的高安全性已得到证实。
