Where does the fat go? How does your body get rid of it?

The fat that was just frozen undergoes apoptosis, or a programmed series of steps that leads to the fat dying off. It then gets broken down into much smaller biological fragments. These fragments are then taken away by your body's circulatory system and disposed of by the immune system. Once that fat had died, it will not be able to rejuvenate again - it is gone forever. 

The Coolsculpting procedure suctions in the skin surrounding the area of fat you want to freezes, then uses controlled cooling (aka cryolipolysis) to drop the temperature of the skin down to where the fat cells die. The body then eliminates the cells in the following weeks. See an expert. Best, Dr. Emer

When a CoolSculpting procedure is performed, the treatment normally will cause about 20-25% of the fat cells in the treated area to be destroyed.  These damaged fat cells are then disposed of by cells in the body called macrophages, which are scavenger cells that engulf old or damaged cells.
