Cool plastic fat dissolving technology is designed based on the principle that fat cells in human body can't stand low temperature. Using the constant low temperature of 4 degrees Celsius, the frozen fat dissolving instrument is placed on the surface of human skin, such as waist, abdomen, back, buttocks and other parts where fat is easy to accumulate. When it is cold, fat cells will self-apoptosis, and they will be gently excreted through the natural metabolic process of the body without external intervention, so as to achieve the effect of slimming.
