KuAn Technology's 4th Generation Thermal Master, with 7 working heads, is a multi-functional device for physiotherapy and body sculpting. It utilizes an ultrasonic head to emit highly focused ultrasound waves onto the skin, targeting different areas of the body. Adjustable energy levels, time, temperature, and modes penetrate skin tissue, rapidly vibrating fat cells. This causes friction within the fat cells, resulting in localized heating and the breakdown of fat cells into water, glycerol, and free fatty acids. These substances then enter the lymphatic system and are excreted through sweat. The heat further warms the body internally, accelerating metabolism and allowing the liver to absorb and convert glycerol and free fatty acids into energy. This process reshapes subcutaneous collagen tissue, creating new tissue layers, resulting in firmer, tighter skin, smoothing wrinkles, restoring elasticity, and preventing skin sagging after weight loss.
