As triglyceride in fats will be converted into solid in particular low temperature, Cryolipolysis system uses precisely controlled cooling energy to the targeted areas for treatment. It selectively targets at certain fat bulges and eliminate fat cells through a gradual process that does not harm the surrounding tissues and reduce unwanted fat. When fat cells are exposed to precisely control cooling, the triglyceride in fats will be converted into solid, and will be crystallizing, aging, and then die. The dead fat cells will be out of body by natural metabolism.
