Injured fat cells undergo apoptosis - that is programmed cell death. Basically, the injured fat cell sends a signal to the immune system. During the 2-month post- treatment period after your cool sculpting, these injured fat cells undergo a controlled and programmed form of cell death, helped along by immune system cells. The material from these cells is taken up and metabolized by the immune system cells. Regarding fat emboli - this is a rare event reported with traditional large-cannula liposuction. I am not aware of any such cases from cool sculpting.
