简介：AbstractRhytides and striae are prominent clinical signs of skin aging. Photoaging, characterized by a thinning epidermis and a decrease in collagens, is the main form of skin aging. Delaying the aging process is a concerning issue for dermatologists. Radiofrequency (RF) is a non-ablative technology used for skin rejuvenation, body contouring, and weight reduction. The selective electro-thermolysis stimulates collagen contraction and neocollagenesis. Compared to traditional cosmetic treatment, it has the advantages of fewer side effects and short patient downtime. This review aims to summarize the efficacy and safety of different RF devices and the limitations during RF treatments. Combinations of RF and other cosmetic technologies are demonstrated. Results have been approving for the various uses of RF, including skin laxity and wrinkles smoothening. However, many studies use subjective ways of evaluation. Further studies are needed to determine the optimization of RF treatments for facial rejuvenation.
