Fat freezing, technically known as cryolipolysis, is an FDA approved non-invasive method of freezing fat cells to get rid of “love handles,” a double chin and other unwanted bulges of fat. It promises to remove 25 percent of fat in a given area, but probably not all in a single treatment. Fat freezing works by using paddles that suction your skin into a cup in order to crystallize underlying fat cells. Each procedure can last from 30 minutes to an hour, depending on the target area. The discomfort involved is minimal although the area treated will first feel very cold and then numb.
