Facial wrinkles and sagging are the most visible signs of aging and can cause profound distress. Microneedle fractional radiofrequency (MFR) is a minimally invasive procedure, which utilizes both microneedling and radiofrequency energy to rejuvenate the skin.
To describe the safety and efficacy of a temperature-controlled MFR device on facial fine lines and laxity.
A retrospective chart & histology review was performed on individuals who received bipolar MFR for facial rejuvenation. A total of 15 Koreans with a median age of 46 years were included. All participants underwent a single treatment session. The results were assessed objectively using serial photography and subjectively based on the participants' satisfaction scores. Histologic changes before, immediately after MFR and at 4 months follow-up was examined. Complications were also recorded.
Partially denatured collagen fibers and dermal shrinkage was observed immediately after MFR whereas an increase in elastin and collagen was noted at 4 months follow-up. 86.7% of recipients considered the results satisfactory. Consensus ratings by two independent dermatologists on the objective outcomes at 4-month follow-up were very much improved (53.3%), much improved (26.7%) and improved (20%). Treatment was well tolerated and did not cause any significant long-lasting discomfort.
Temperature-controlled bipolar MFR is a minimally invasive treatment option to consider for facial fine lines and laxity via neo-collagenesis and neo-elastogenesis. The procedure was safe and clinically effective.
面部皱纹和松弛是衰老最明显的迹象，会引起极大困扰。微针分数射频（MFR）是一种微创手术，它利用微针和射频能量来使皮肤恢复活力。
描述一种温度控制的MFR设备对面部细纹和松弛的安全性和有效性。
对接受双极MFR进行面部年轻化治疗的个体进行回顾性病历和组织学审查。共纳入15名韩国人，中位年龄为46岁。所有参与者均接受单次治疗。结果通过系列摄影进行客观评估，并根据参与者的满意度评分进行主观评估。检查了MFR治疗前、治疗后即刻以及4个月随访时的组织学变化。还记录了并发症。
MFR治疗后即刻观察到部分变性的胶原纤维和真皮收缩，而在4个月随访时发现弹性蛋白和胶原蛋白增加。86.7%的接受者认为结果令人满意。两位独立皮肤科医生对4个月随访时客观结果的共识评级为非常改善（53.3%）、改善很多（26.7%）和有所改善（20%）。治疗耐受性良好，未引起任何明显的长期不适。
温度控制的双极MFR是一种微创治疗选择，可通过新胶原生成和新弹性生成来改善面部细纹和松弛。该手术安全且临床有效。
