Fine lines and rhytides are clinically evident signs of photodamage. Traditionally, ablative and nonablative lasers have been used for nonsurgical facial rejuvenation, but their side effects and downtime have limited their use.
Radiofrequency (RF) is novel nonablative technology originally used to target photodamage. It differs from lasers in that it uses an electric current rather than a light source. It is frequently used in dermatology to treat skin laxity, rhytides, acne vulgaris and scarring, and cellulite. The goal of this review is to summarize the various types of RF devices and their uses and to determine the evidence-based efficacy of these devices.
This article reviews the current literature on RF, its uses and clinical effectiveness, and a practical guide for application of the assorted RF devices.
Results have been favorable for the different clinical uses of RF, but many studies are nonrandomized, noncomparative trials that use subjective means of evaluation. Overall, nonablative RF is a safe, tolerable, and effective tool for skin rejuvenation and cellulite treatment that produces modest results. RF should serve as an alternative but not as an equivalent substitute to surgery.
细纹和皱纹是光损伤的临床明显迹象。传统上，消融性和非消融性激光已被用于非手术面部年轻化，但它们的副作用和停机时间限制了它们的使用。
射频 (RF) 是一种新颖的非消融性技术，最初用于治疗光损伤。它与激光不同，它使用电流而不是光源。它在皮肤科中常用于治疗皮肤松弛、皱纹、寻常痤疮和疤痕以及蜂窝织炎。本综述的目的是总结各种类型的 RF 设备及其用途，并确定这些设备的循证疗效。
本文回顾了关于 RF 及其用途和临床效果的当前文献，并提供了应用各种 RF 设备的实用指南。
RF 在不同的临床用途中取得了良好的效果，但许多研究是非随机的、非对照试验，使用的是主观评估手段。总体而言，非消融性 RF 是一种安全、耐受且有效的皮肤年轻化和蜂窝织炎治疗工具，效果适中。RF 应作为手术的替代方法，但不能作为替代方法。
