As triglyceride in fats will be converted into solid in particular low temperature, this machine uses precisely controlled cooling energy to the target 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 they will be Crystallization, aging and then die. The dead fat cells will be out of body by natural metabolism.
