BRAND NEW MACHINE, IN BOX, UNOPENED. Effective and Safe Fat Reduction? The device utilizes 40K ultrasonic cavitation to break down fat cells without damaging surrounding tissue, making it a safe, non-invasive alternative to traditional fat reduction methods. Advanced Functions? Including frequency tracking function, it can automatically adjust the ultrasonic frequency to extend the service life of the equipment and ensure long-term stable performance. User-friendly design? Using color touch screen, easy to operate, ergonomic handle, comfortable to use, simple interface, suitable for both home use, as well as beauty salons and spas and other professional places. Safety and Comfort Revolution? Ultrasonic cavitation works deeply and non-invasively without damaging the skin: the particles emitted by our machines are not absorbed by the fat cells, just as RF energy is dispersed in a much shallower way (dermis and epidermis).
