Working principle and efficacy of ultrasonic beauty equipment

Working principle and efficacy of ultrasonic beauty equipment

1. Working principle

Ultrasound refers to mechanical vibration waves with frequencies exceeding 20,000 Hz. The vibration wave has mechanical, thermal and chemical effects. The ultrasonic beauty machine uses the characteristics of strong ultrasonic penetration and can penetrate into the subcutaneous 4-6mm to perform physical therapy on the human body and face to achieve the purpose of losing weight, body sculpting, whitening and improving skin condition. After the launch of the ultrasonic facial cleanser, it is deeply loved by women and has become a good tool for many beauty salons and customers.

2. Features of Ultrasound

Ultrasound can make skin cells vibrate, have good massage effect, change cell volume, improve local blood and lymph circulation, improve cell permeability, tissue metabolism and regeneration ability, soften tissue, stimulate nervous system and cell function, make skin Shiny and elastic.

Ultrasound is characterized by lower frequency, deeper penetration, but less skin absorption (skin thickness varies at different sites). The ultrasound depth of 1 MHz is to reach the muscle layer, and the penetration depth of 3 MHz is from the dermis to the subcutaneous tissue. Ultrasound frequency is about 3mm, which can act on the dermis more accurately. Collagen, hyaluronic acid and elastic fibers are the dermis of our skin.

The commonly used ultrasonic beauty instruments on the market are generally around 1MHz. Because the penetration depth is deep, the real cortex absorbs very little, and in fact the effect is very limited. Ultrasound is widely used in medical ultrasound, industrial ultrasonic cleaning machine, sonar, radar and other fields because of its safety characteristics.

3. Three main effects of ultrasonic beauty equipment

1) Mechanical effect: 

The ultrasonic power is strong. When it acts on the face, it can make the skin cells vibrate, make a subtle massage effect, and change the cell volume, to improving the circulation of local blood and lymph, to improving the metabolism and regeneration of the tissue, and making the skin with shiny and elasticity.

2) 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, the analgesic effect can be achieved, and the spasmodic muscle fibers can be relaxed to makes 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 thermal sensation.

3) 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.

4. Precautions for the use of ultrasonic beauty equipment

1) Before using the ultrasonic beauty machine, the skin of the physiotherapy area should be cleaned to prevent dirt from entering the skin with the ultrasonic wave or preventing the penetration of the ultrasonic wave.

2) It is best to use a medium with a certain viscosity, which is conducive to the better fusion of the ultrasonic wave and the skin, and prevents the reflection caused by the gap and is not conducive to absorption.

3) Each physiotherapy segment is generally 15 to 20 minutes. Too long or improper use will cause skin fatigue and poor absorption. The user can choose the appropriate time according to the size of the physiotherapy area.

4) The degree of probe heat does not represent the output of ultrasonic power; liquids or drugs with small concentrations should not penetrate directly, otherwise it will easily cause dry skin.

5) When using the instrument, the probe should not be close to the eye, cannot pass through the eye, and pregnant women and patients with severe heart disease are prohibited.

6) Media such as water, oil, etc. shall not penetrate into the inside of the instrument, and shall not be knocked, knocked or dropped heavily to avoid damage to the instrument.

7) After using the ultrasonic beauty instrument, please clean the probe and disconnect the power supply in time.

8) Pregnant women and patients with severe heart disease cannot use it.
