Working principle: Through the compression and stretching of 1 MHz ultrasonic waves, micro-vibration massage is formed at 1 10,000 times per second. Just like thousands of hands are massaging, under the action of high-speed vibration and various waveforms, the cells in the deep skin are quickly heated, which accelerates the circulation of blood and body fluids, promotes metabolism and restores the cell activity of the body. And countless tiny bubbles are formed in body fluids, which wrap the toxins and wastes in the body, scatter the excess fat under the skin and shake it, and finally excrete it. It has multiple effects of enhancing cell activity and permeability, firming skin, improving skin problems, burning fat and slimming.
