Ultrasound Cavitation is a relatively new aesthetic treatment. Using leading-edge technology it converts fat cells into liquid which can then be naturally drained by the body’s own natural filtration system. Generally, one fat cavitation treatment lasts 25 – 30 minutes where a single part of the body is treated. 72 hours must pass between each session so that the body can eliminate the fat. The minimum suggested a number of fat cavitation sessions are between 6 and 10.
