HIFU (High Intensity Focused Ultrasound) energy can be used to penetrate through the skin layers and into the targeted fat tissue without harming skin or surrounding tissues. Low intensity ultra sound requires multiple treatments whilst HIFU energy non-invasively destroys targeted subcutaneous fat and delivers uniform, predicable after a single 1-hour treatment. The average waistline reduction after just one single 1-hour treatment is about 1 inch (2.5cm) which typically means one dress size.
