The Principle and Clinical Application of Radiofrequency Devices in Dermatology / 대한피부과학회지

ABSTRACT

Radiofrequency (RF) device is a novel non-ablative technology which differs from laser devices that uses an electric current rather than a light source. RF device can deliver thermal energy to the dermis and stimulate neocollagenesis and dermal collagen remodeling, so that it is frequently used in cosmetic dermatology for skin rejuvenation. However, some questions remain regarding the optimal treatment parameter such as energy levels and number of passes. Unwanted adverse effects like burn and erythema with edema would occur at any time during the procedures. Therefore, it is very important that RF should be performed by skilled and well-trained clinicians. In this review, we summarized the basic principles of RF and its use to determine the evidence-based efficacy. In addition, various adverse effects and management of them will be addressed in this article.
