How Does it Work? The truSculpt iD system delivers monopolar radiofrequency energy non-invasively to specific areas, removing unwanted surface fat (located above the muscle). There is no anesthesia needed and little to no “downtime.” The precise temperature delivery and monitoring allow it to target fat cells optimally while maintaining a cooler skin temperature. As a result, treatments are both more comfortable and effective than other devices that use heat energy. In clinical studies, patients showed an average of 24% fat reduction after a single truSculpt iD session (in contrast to most other systems, which involve a series of treatments to achieve up to the same level of fat reduction). The fat cells removed by truSculpt iD are gone permanently (in a process called lipolysis).
