Fat freeze: Gel pads are placed over this flab to prevent skin damage as the −5*C cooling plates lower the temperature of fat cells gradually. Fat cells freeze more quickly than skin cells, so the thermoelectric cooling is regulated to be cold enough to kill fat, but not cold enough to give people frostbite. After an hour session, the cold flab is often massaged, and that’s it.
After the cooling process kills the fat cells, they’re attacked by white blood cells, which convert them to triglycerides that are then metabolized by the liver and eliminated. And then patients pass the fat out through urine, bowl movements and sweat.
