I want to permanently kill or remove fat cells. (adipocytes) What is the difference between "Ultrasonic cavitation" and "Liposonix". Both sounds same for me. My doctor said "Ultrasonic cavitation" does not remove fatcells permanantly. However it is confusing to me because some doctors say "Ultrasonic cavitation" disrupts fatcells permanantly. So please explain which is effective method. ( I don't care about the released fat liquid from disrupted fat cells. I only care about fat cells.)
