Radiofrequency technology has emerged as a treatment for aesthetic rejuvenation.
To examine radiofrequency for facial and neck rejuvenation, clinical studies were assessed on effectiveness and safety of radiofrequency for acne, acne scars, and facial aging by subjective and objective measures.
A systematic literature review was performed. Eligibility criteria included articles in English, primary literature, clinical or ex vivo studies, use of radiofrequency, and face or neck treatment. Ablative techniques, home-use devices, combined modalities, and studies unrelated to rejuvenation were excluded. All studies were appraised for quality and biases.
We identified 121 articles. Radiofrequency effectively treated acne by reducing sebum levels and lesion count and improving acne scars. Radiofrequency demonstrated a volumetric reduction in facial fat, and improved skin laxity, elasticity, and global skin aesthetic. Patient satisfaction was higher for those desiring modest rejuvenation. There were histological changes consistent with repair response, neocollagenesis, and neoelastinogenesis. Radiofrequency was safe apart from one patient who developed a neck fistula.
Most studies demonstrated radiofrequency treatment of acne, scars, or facial rhytids had positive subjective improvement ratings. Objective studies demonstrated reduction of acne, decreased scarring, lifting effect, improvement in elasticity and collagen, volumetric fat changes, and wrinkle reduction.
射频技术已成为一种美容焕肤的治疗方法。
评估射频技术对面部和颈部年轻化的效果和安全性，通过主观和客观测量评估射频治疗痤疮、痤疮疤痕和面部衰老的临床研究。
进行了系统的文献回顾。纳入标准包括英文文献、原始文献、临床或离体研究、使用射频以及面部或颈部治疗。排除消融技术、家用设备、联合治疗模式以及与焕肤无关的研究。对所有研究进行质量和偏倚评估。
我们共确定了 121 篇文章。射频通过降低皮脂水平和皮损计数以及改善痤疮疤痕，有效治疗痤疮。射频显示出面部脂肪的体积减少，并改善皮肤松弛、弹性和整体皮肤美观。对于那些希望适度焕肤的患者，满意度更高。有组织学变化与修复反应、新胶原生成和新弹性蛋白生成一致。射频是安全的，除了一名患者出现颈部瘘管。
大多数研究表明，射频治疗痤疮、疤痕或面部皱纹具有积极的主观改善评分。客观研究表明，痤疮减少，疤痕减少，提升效果，弹性和胶原蛋白改善，脂肪体积变化和皱纹减少。
