HIFU operation
1. Adjust the depth and energy. Select 4.5mm depth at the beginning of the operation, and use 3.0 depth for the third and fourth times.

2. Test the energy intensity: First, pull the right lower jaw to the corner of the mouth at a uniform speed. If there is no feeling, increase the mechanical wave/EMS energy. It is normal to feel tingling, numbness or soreness during the operation. The energy needs to be reduced when operating on the nose (the energy size should be adjusted according to personal conditions), because the position with more bones is more sensitive and the energy received will be lower (different operation parts have different energy sizes, and the energy needs to be adjusted according to personal conditions).

3. Normal skin: First use. It is recommended to use low intensity for mechanical waves and EMS energy. During operation, adjust the mechanical waves and EMS energy to the maximum range that the individual can bear according to the feeling.

4. Red bloodshot skin: It is recommended to only turn on the mechanical wave for the first use. After 3-4 times of use, you can turn on RF and mechanical waves at the same time. The RF energy starts from the lowest intensity and the power of the mechanical wave is adjusted according to the individual's maximum tolerance.

5. Sensitive skin with thin stratum corneum: The lowest mechanical wave and RF power are recommended for the first use. After 2-3 uses, the energy can be adjusted to the maximum tolerance of the individual according to the individual skin condition.

6. During the treatment, the medium needs to be applied to the treatment area, and the cartridge needs to be close to the skin. At a regular speed and lifting method, the medium needs to be replenished after absorption or drying.

7. A full face operation generally takes 30-45 minutes. (The operation time varies according to the size of the face.)
