“Radio-frequency skin tightening”的意思、由来-开放百科全书

By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.^[7]

Several companies manufacture RF devices, including D-Finitive Evo by Beco Medical V-Form by Viora, Thermage by Solta Medical, Venus Freeze by Venus Concept, VelaShape by Syneron, Exilis by BTL, and 3DEEP by Endymed. Alternative techniques include Laser Resurfacing and certain Ultrasound alternatives. Typically, treatment requires a series of 8-12 treatment sessions lasting 30–45 minutes. Devices have different penetration depths depending on the number of electrodes (monopolar, bipolar, or unipolar).^[8]

Side effects

Due to radiation of high-energy radio frequency, several patients have reported pain requiring sedation during the procedure. The process also requires extreme care in its execution for improper application may result in dents on the skin surface due to uneven healing responses on the skin. Many effects including fat necrosis and atrophic scarring have also been reported, although several new techniques have overcome this obstacle. With the application of a vacuum at the point of application, the burning and crusting was reportedly reduced.
