Using the sound wave with a frequency of 4 MHz emitted by the strong sound wave head gathering strong sound waves, human adipocytes can produce a strong impact and friction movement between adipocytes after entering the human body, which can effectively consume heat, water and shrink adipocytes. 

Cavitation Principle of Ultrasound

Tens of thousands of tiny bubbles, namely cavitation bubbles, are produced by vibration of liquid. These bubbles grow in the negative pressure region formed by the longitudinal propagation of ultrasound, and close rapidly in the positive pressure region, thus being compressed and stretched under alternating positive and negative pressures.

The bubbles will be compressed until burst, which will generate huge instantaneous pressure, generally up to tens of MPa to hundreds of MPa, and produce strong vibration and noise.

In addition, when sound waves vibrate, it can make adipocytes smaller. Strong crack will come along, cells will burst instantly, adipocytes reduce, so as to achieve the effect of fat removal. 

It only aims for low-density adipose tissue in a specific frequency, and protects high-density tissue such as vascular and nerve tissue.
