The frequency of sound waves that human ears can hear is 20 to 20,000 Hz. When the vibration frequency of the sound wave is greater than hz or less than 20hz, we cannot hear it. Therefore, we call sound waves with frequencies higher than hz as “ultrasound.”
The lower the ultrasonic frequency, the stronger the penetration. The ultrasonic frequency generally used in the beauty industry is 1-3mhz.
Ultrasound has the characteristics of good directionality, strong penetrating ability, easy to obtain concentrated sound energy, and long transmission distance. Therefore, it is used in more and more industries.
Beauty equipment ultrasonic technology has been introduced into the beauty session since the 1980s. It has been popularized and promoted for its wide range of treatment, quick effect, high cure rate, and easy operation. It has become the most practical and popular equipment among many beauty instruments. With the advancement of science and technology, a new generation of professional ultrasonic beauty equipment turned out, bringing its excellent quality, powerful functions, and luxurious appearance to quickly sweep the beauty industry.
The application of ultrasound in the beauty industry mainly has the following functions:
1. Mechanical effect: 1 million mechanical vibrations per second, make every part of the affected part vibrate, play a unique cell massage effect, improve cell metabolism, enhance cell vitality, promote blood circulation, and improve skin Tissue nutrition, make the skin rosy and increase elasticity.
2. Warming effect: The warming effect of ultrasound can make blood circulation vigorous by causing changes in blood vessel function and metabolic process, reducing cell excitability, and producing analgesic effect. It relaxes the spasm skin and has an anti-spasm effect.
3. Chemical effect: Ultrasound has the effect of strengthening catalysis and accelerating metabolism. The ph value can be changed to alkaline. Facilitate the penetration of drugs and improve the bactericidal ability of drugs.
