CoolSculpting uses a scientifically developed mechanism known as Cryolipolysis. Each cooling session effectively eliminates fat cells. During the treatment, proprietary applicators isolate the stubborn bulge of fat and subject it to precise cooling. The temperature freezes fat cells causing them to rupture and trigger a biological process known as apoptosis or cell death. Several weeks after, the body undergoes an immune response that collects the dead cells and removes them from the body. Once those cells are removed, they can never return. As a result, CoolSculpting leads to lasting fat reduction results.
