The principle of ultrasonic beauty instrument is very similar to that of light wave instrument, which stimulates the rapid reproduction of mother cells at the bottom of skin, so many people feel that the effect is obvious after using it once, and the skin has indeed improved in a short time.
However, this kind of stimulation will violate the natural growth law of cells, hinder the metabolism of the skin itself, and a large number of cells in the body will die because they can't get enough nutrition. The skin will also become thinner and thinner, with red blood and weak resistance.
Generally speaking, short-term use of ultrasonic beauty instrument is not harmful, but there is no secret of relaxing beauty in the world, and long-term use will do some harm to our health. The best way to improve skin beauty is through healthy diet and exercise.
Extended data
Matters needing attention in using ultrasonic beauty instrument:
1. Before using the instrument, clean the skin at the physiotherapy site to prevent dirt from entering the skin with ultrasonic waves or preventing ultrasonic waves from penetrating.
2. It is best to use a medium with a certain viscosity, which is conducive to the better integration of ultrasound and skin, and avoids the reflection caused by gaps that is not conducive to the absorption of sound energy.
3. Each physiotherapy session is generally 15 ~ 20 minutes. Too long or improper use will cause skin fatigue and malabsorption. Users can choose the appropriate time according to the size of the physical therapy site.
4. The degree of probe heating does not represent the output of ultrasonic power; Small concentrations of aqua or drugs should not directly penetrate, otherwise it will easily cause dry skin.
