Once the fat cells are frozen through the process of cryolipolysis, the body naturally eliminates them as waste. Fat cells removed through CoolSculpting do not return, as fat cells cannot regenerate. This is more effective than dieting or exercise, methods that can only shrink the size of the fat cells rather than completely eliminating them. With CoolSculpting, even if the patient gains weight in the future, the treated areas will still remain toned and lean.
