1. Mechanical function
The ultrasonic power is strong and the energy is large, acting on the face can cause the skin cells to vibrate, produce a fine massage effect, change the cell volume, thereby improve the circulation of local blood and lymph, and strengthen the cells The permeability improves the metabolism and regeneration of the tissue, softens the tissue, stimulates the nervous system and cell function, and makes the skin shiny and elastic.
2. Warming effect
Through the warming effect of ultrasonic, ultrasonic beauty massager can increase the temperature of the skin surface, accelerate blood circulation, increase the nutrients of skin cells, reduce nerve excitability, play an analgesic effect, relax spasm muscle fibers and play an antispasmodic effect. Ultrasound heat is endogenous heat, 79% to 82% of the heat is carried away by the blood self-acting area, and 18% to 21% is dispersed to adjacent tissues by heat conduction. Therefore, the patient has no obvious heat sensation.
3. Chemical effect
Ultrasound can strengthen the catalytic ability, accelerate the metabolism of skin cells, change the pH value of the tissue to the 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 skin to absorb nutrients, facilitate the penetration of drugs into the bacteria, and improve the sterilization ability.
1. Clean the skin of the physiotherapy site before using the face beauty machine to prevent dirt from entering the skin with ultrasound or preventing the penetration of ultrasound.
2. The medium used in the beauty device should have a certain viscosity, which is conducive to the better integration of ultrasound with the skin, and prevents the gap from causing reflection and unfavorable absorption of sound energy.
3. Each physiotherapy section usually lasts 15-20 minutes. If the beauty device is used for a long time or improperly used, the skin will be overworked and has malabsorption. The user can choose the appropriate time according to the size of the physiotherapy site.
4. The warmth degree of the massage head does not represent the output of the ultrasonic power; the liquid or medicine with low concentration should not be directly penetrated, otherwise it will easily cause dry skin.
5. When using the ultrasonic facial beauty device, the massage head should not be close to the eyes, can not pass the eyeball, pregnant women and people with severe heart disease are prohibited.
6. Water, oil and other media must not penetrate into the inside of the instrument, and must not be impacted, beaten, or dropped to avoid damage to the instrument.
7. After using the ultrasonic beauty massager, please clean the massage head in time and disconnect the power supply.
