Cryolipolysis, also known as fat freezing surgery, uses triglycerides in fat to become solid at temperatures as low as 5 degrees Celsius. Cryoenergy is delivered to the affected area through a non-invasive cryoenergy extraction device to target and eliminate fat cells in the affected area. After cooling to a certain low temperature, triglycerides change from liquid to solid, and after crystallization and aging, they are gradually excreted from the body through metabolism. The body fat gradually decreases, thus achieving a body shaping effect.
