Mechanical effect: the ultrasonic wave has strong power and large energy.
When it acts on the face, it can make the skin cells vibrate, produce micro
massage effect, change the cell volume, so as to improve the circulation of
local blood and lymph, enhance the permeability of cells, improve the metabolism
and regeneration ability of tissues, soften tissues, and stimulate the nervous
system and cell function, Make the skin shiny and elastic.
Warming effect: through the warming effect of ultrasound, it can improve
the temperature of the skin surface, accelerate the blood circulation, increase
the nutrients of skin cells, reduce the nerve excitability, relieve pain, relax
the spasmodic muscle fibers and relieve spasm. Ultrasonic heat is endogenous
heat. 79% ~ 82% of the heat is transported by the blood self action area, and
18% ~ 21% is dispersed into adjacent tissues by heat conduction. Therefore, the
patient has no obvious thermal sensation. Chemical action: ultrasound can
strengthen the catalytic ability, accelerate the metabolism of skin cells,
change the pH value of tissue to alkaline direction, and reduce the acidosis and
pain associated with skin inflammation. Ultrasound can improve the permeability
of cell membrane, depolymerize nutrients and drugs, facilitate the skin to
absorb nutrients, facilitate the penetration of drugs into bacteria, and improve
the bactericidal ability.
Precautions for use of ultrasonic beauty instrument
1. Before using the instrument, the skin of the physiotherapy part should
be cleaned to prevent dirt from entering the skin with the ultrasonic wave or
prevent the penetration of the ultrasonic wave.
2. It is better to use the medium with a certain viscosity, which is
conducive to the better integration of ultrasonic and skin, and prevent the
reflection caused by the gap from being unfavorable to the absorption of sound
energy.
3. Each physiotherapy section is generally 15 ~ 20 minutes. Too long or
improper use will cause skin overwork and malabsorption. The user can select the
appropriate time according to the size of the physiotherapy site.
4. The warm degree of massage head does not represent the output of
ultrasonic power; Low concentration of water or drugs should not be directly
penetrated, otherwise it is easy to cause dry skin.
5. When using the beauty instrument, the massage head shall not be close to
the eyes, cannot pass through the eyes, and is prohibited for pregnant women and
patients with serious heart disease.
6. Water, oil and other media shall not penetrate into the inside of the
instrument, and shall not be hit, knocked or dropped again to avoid damaging the
instrument.
7. After using the ultrasonic beauty instrument, please clean the massage
head in time and disconnect the power supply.
