Zeltiq's CoolSculpting system uses a patented technique called cryolipolysis to send fat cells into slow cell death (apoptosis) by lowering their temperature to the point where they freeze. The drop in temperature, however, is not enough to adversely affect surrounding tissue because fat cells are more prone to cold injury than other cell types. The cells take days to weeks to die. After the cells have begun to destruct, their components are consumed by macrophages, which are part of our lymphatic system and are designed to digest and expel cellular debris. The cell components are then excreted from the body via the urine. Thus, the fat cells have not been shrunk, they have been destroyed and removed from the body. Long-term studies suggest that these cells cannot re-appear. However, if you over-eat, the fat cells that remain in the area treated by CoolSculpting can expand, leading to the development of another fatty deposit. That's why it's so important to be committed to a healthy diet and exercise regimen even before having a CoolSculpting treatment. Please find a board-certified dermatologist who has been certified by Zeltiq as a CoolSculpting practitioner to remove your stubborn fat so you'll be beach-ready by summer.
