The piezoelectric ceramic element in the ultrasonic beauty instrument refers to a mechanical vibration wave whose frequency exceeds 20,000 Hz and cannot cause normal human hearing, and the vibration wave has mechanical action, warming action and chemical action. The ultrasonic beauty instrument utilizes the three major functions of ultrasound to treat the face of the human body for cosmetic purposes.


The mechanical function of the piezo disk crystal in the ultrasonic beauty instrument: the ultrasonic power is strong and the energy is large. The action on the face can cause the skin cells to vibrate, produce a fine massage effect, change the cell volume, thereby improving the local blood and lymph fluid. Circulation, enhance cell permeability, improve tissue metabolism and regeneration, soften tissue, stimulate nervous system and cell function, and make skin shiny and elastic.


The warming effect of the piezoceramic disk transducer in the ultrasonic beauty instrument: by the warming action of the ultrasonic wave, 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 lowered, and the analgesia can be achieved. The effect is to relax the muscle fibers of the tendon and play a role in relieving phlegm. The heat of the ultrasonic wave is endogenous heat, and 79% to 82% of the heat is transported away from the action area by the blood, and 18% to 21% is dispersed by heat conduction to the adjacent tissue. Therefore, the patient has no obvious thermal sensation. Chemical action: Ultrasound can enhance the catalytic ability, accelerate the metabolism of skin cells, change the pH of the tissue to the alkaline direction, and alleviate 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 cells, and improve the bactericidal ability.


The specific functions of the ultrasonic beauty instrument are as follows: softening the blood clot and eliminating the "red face". It is used for facial microvascular deformation, facial redness caused by blood circulation disorders, erythema, and facial erythema or rosacea caused by aphid infection.


Ultrasonic beauty instrument should pay attention to the following points when using: the degree of heat of the probe does not represent the output power of the sound wave, too hot and easy to burn the skin; the liquid medicine with too small concentration should not be directly infiltrated, otherwise it may cause dry skin; The probe cannot pass through the eyeball, and the upper eyelid cannot be massaged; pregnant women and patients with severe heart disease cannot use it.
