　　Mechanical effect: The ultrasonic power is strong and the energy is large. When it acts on the face, it can make the skin cells vibrate, produce a fine massage effect, and change the cell volume, thereby improving the circulation of local blood and lymph, enhancing the permeability of cells, and improving the Tissue metabolism and regeneration ability, soften tissue, stimulate nervous system and cell function, make skin shiny and elastic.

　　Warming effect: Through the warming effect of ultrasonic waves, the temperature of the skin surface can be increased, the blood circulation can be accelerated, the nutrients of the skin cells can be increased, the nerve excitability can be reduced, and analgesic effect can be achieved. Antispasmodic effect. The heat of ultrasound is endogenous heat, 79% to 82% of the heat is transported away by the blood from the action area, and 18% to 21% is dispersed to adjacent tissues by heat conduction. Therefore, the patient has no obvious heat sensation. Chemical effect: Ultrasound can strengthen the catalytic ability, accelerate the metabolism of skin cells, change the pH value of the tissue to an alkaline direction, and reduce the acidosis and pain associated with skin inflammation. Ultrasound can improve the permeability of cell membranes, depolymerize nutrients and drugs, facilitate the absorption of nutrients by the skin, facilitate the penetration of drugs into the bacteria, and improve the sterilization ability.
