KuAn Technology's 80K Fat-Burning Device uses seven working heads to emit highly focused ultrasound waves up to 80,000 Hz onto the skin. Targeting different areas of the body, the energy level is adjusted to penetrate skin tissue and rapidly vibrate 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 heats the body's internal systems, accelerating metabolism and allowing the liver to absorb and convert the glycerol and free fatty acids into energy. This process reshapes subcutaneous collagen tissue, creating new tissue layers, resulting in firmer, tighter skin, smoothing wrinkles, and restoring elasticity, preventing sagging skin after weight loss.
