The Cryoskin machine thermally shocks the cells due to its ability to alternate rapidly between periods of skin warming and cooling. First, the heat is applied for 2 minutes on the treatment area. Heating allows for the fat cells to rise to the surface. They are then quickly targeted with a 12-minute cold treatment of each area. The water within the cells quickly expands from the cold shock, causing the cells to burst. The cells are then excreted naturally by the body’s lymphatic system for permanent fat loss.
