Ultrasonic wave refers to mechanical vibration wave with frequency over 20000Hz, which has mechanical, thermal and chemical effects. Ultrasonic beauty instrument uses the characteristics of strong ultrasonic penetration and deep subcutaneous 4 ~ 6 cm to perform physical therapy on human body and face, so as to achieve the purpose of losing weight, shaping, whitening and improving skin quality.
This behavior, which violates the skin's own metabolic cycle, will do harm to cells. A large number of cells will die because they can't get enough nutrition, and the skin will become very thin and the resistance will decrease. It is recommended to cooperate with internal adjustment and external support and pay attention to diet conditioning.

Matters needing attention in using ultrasonic beauty instrument:
1. Before using the instrument, clean the skin at the physiotherapy site to prevent dirt from entering the skin with ultrasonic waves or preventing ultrasonic waves from penetrating.
2. It is best to use a medium with a certain viscosity, which is conducive to the better integration of ultrasound and skin, and avoids the reflection caused by gaps that is not conducive to the absorption of sound energy.
3. Each physiotherapy session is generally 15 ~ 20 minutes. Too long or improper use will cause skin fatigue and malabsorption. Users can choose the appropriate time according to the size of the physical therapy site.
4. The degree of probe heating does not represent the output of ultrasonic power; Small concentrations of aqua or drugs should not directly penetrate, otherwise it will easily cause dry skin.
5. When using the instrument, the probe shall not be close to the eyes or pass through the eyeball. Pregnant women and patients with severe heart disease are prohibited.
6, water, oil and other media shall not penetrate into the instrument, can't knock and fall so as not to damage the instrument.
7. After using the ultrasonic beauty instrument, please clean the probe in time and disconnect the power supply.
