Ultrasonic cavitation is performed with noninvasive machines that target specific body areas with low-frequency sound waves (they are what put the “ultrasonic” in “ultrasonic cavitation”) and, in some cases, light suction.
This process heats and vibrates the layer of fat cells below the skin’s surface. The pressure eventually causes the fat cells to liquefy and release their contents into the bloodstream. Proponents of the procedure believe that the body is then able to process these fatty acids through its proverbial "waste-disposal plant”, the lymphatic system.
Radio-frequency skin Tightening is an aesthetic technique that uses radio frequency (RF) energy to heat skin with the purpose of stimulating cutaneous collagen, elastin and hyaluronic acid production in order to reduce the appearance of fine lines and loose skin. The technique induces tissue remodeling and production of new collagen and elastin. The process provides an alternative to facelift and other cosmetic surgeries. 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.
Results can vary greatly from patient to patient. However, most proponents of ultrasonic cavitation claim that you’ll see:
Although most practices that offer ultrasonic cavitation claim you’ll see results after the first session, they also caution that between 8 and 12 sessions are needed for optimum results. The exact number of treatments needed will vary due to factors such as age, weight, and the area being treated.
