The area to be sculpted is filled with a special saline solution which helps to numb the site and shrink the blood vessels. This helps to minimise blood loss, thereby giving reduced bruising. A small probe transmitting sound energy (similar to that used for cataract removal from the eye) fragments fatty tissue, whilst leaving other important tissues intact. The liquified fat is then removed by a suction process. Pain, swelling and bruising are usually less than with traditional liposuction.
