State-of-the-art CoolSculpting technology destroys unwanted fat cells without damaging surrounding tissue and skin. When fat cells are destroyed, they do not renew themselves. Once they are gone, they are gone for good and no longer able to accumulate and store fat. It comes down to the difference between weight loss and fat reduction. Fat cells can shrink or expand, but they cannot replicate. When you lose weight, your fat cells shrink but still have the potential to expand if you regain the weight you lost. With CoolSculpting fat reduction, on the other hand, fat cells are destroyed and removed through the natural processes of the body. The fat cells will not return, and your body does not produce new fat cells to replace them.
