Nowadays, many people like to use hair removal devices to remove hair. The effect of hair removal devices is very good. Many people plant grass. There are many hair removal devices on Taobao. I don’t know about the hair removal devices on Taobao. Is it really useful?
Are the hair removal devices on Taobao useful?
There are many kinds of hair removal devices on Taobao. We cannot simply answer whether they are useful or useless, because there are various types of hair removal devices on Taobao. Each mechanism of action and spectrum is also different, so we cannot easily draw conclusions about whether it is useful or not. However, whether the hair removal device on Taobao is useful or not depends on its working principle. Generally, the hair removal devices that are useful on Taobao are those that truly use the selective photothermal dynamics of lasers, photons (strong pulsed light and weak pulsed light), home light hair removal (HPL), and Elos (photoelectric combination). Hair removal device for hair removal. Because only in this way can the light emitted by the instrument pass through the surface of the skin and reach the roots of the hair follicles. The melanin in the hair follicles will also selectively absorb light of specific wavelengths. The absorption of light energy is converted into heat energy, thereby destroying the hair follicles and causing the hair follicles to become flaky. Hair stops growing.
The principle of hair removal equipment
1. The principle of hair removal equipment: laser hair removal
Equipment that uses laser as hair removal energy is an important branch of hair removal equipment. , Laser hair removal is based on the principle of selective photothermal dynamics. The laser wavelength energy can pass through the surface of the skin and reach the root of the hair follicle. Then the energy in the hair follicle will be absorbed and converted into heat energy that destroys the hair follicle tissue, thereby allowing the hair follicle to be damaged. Hair in the anagen phase is burned and undergoes apoptosis. The laser will not damage the surrounding tissue while working on the hair follicles. It is relatively safe under the premise of regular operation.
Representatives of laser hair removal equipment: Laser hair removal equipment generally uses the American Lighsheer vacuum hair removal equipment and the Israeli Feiton freezing point hair removal equipment, both of which use 810nm semiconductor laser. The most classic laser hair removal instrument is the Israeli Feidon freezing point hair removal instrument with a wavelength of 810nm. This requires gel application.
2. The principle of hair removal equipment: photon hair removal
Photons are different from lasers. Photons refer to strong pulsed light. Photon hair removal equipment uses the characteristics of strong pulsed light energy to absorb melanin. When the strong pulsed light reaches a certain accumulation amount in the hair follicle, it will generate heat energy. This kind of heat energy is enough to destroy hair follicle cells, causing the hair in the growth phase to be lost by skin cancer and lose its vitality, thereby achieving the effect of hair removal.
Representatives of photon hair removal instruments: The photon hair removal instrument is mainly the IPL Quantum photon hair removal instrument from American Scientific Medical, which is also the world's largest medical laser company and a leader in photon technology.
How to choose a hair removal device on Taobao
1. Choose an FDA-certified hair removal device
If you want to buy a hair removal device on Taobao, then It is best to choose a hair removal device that has been approved by the FDA. Because the U.S. FDA is an authoritative international medical review agency and the highest law enforcement agency authorized by the U.S. Congress to specialize in food and drug management. Household hair removal devices certified by it are more quality-guaranteed. Therefore, when selling hair removal devices on Taobao, hair removal devices certified by FDA should be the first choice.
2. Choose a hair removal device with a relatively long spectrum
When girls choose a hair removal device on Taobao, it is best to choose the one with a relatively long spectrum. Because the longer the spectrum, the safer it is for dark skin, and the ability to penetrate the skin will be stronger, making it easier to damage hair follicles. Generally speaking, lasers reaching 810nm can have a better effect on removing coarse hair, so beauty seekers should try to choose lasers with a wavelength above 500nm.
3. Choose a hair removal device with a larger lamp head area
When girls choose a hair removal device on Taobao, it is best to choose a hair removal device with a larger lamp head area, because the lamp head The size of the lamp determines the light output area. In addition, the larger the lamp head area, the more convenient it is to use.
4. Choose a hair removal device that lights up more often
The number of lights up is also an important indicator when choosing a hair removal device on Taobao. When choosing, girls are best to use A hair removal device that lights up more times, because the number of times it lights up directly determines the service life of the hair removal device. However, light intensity and the number of luminescence cannot be achieved at the same time, because the greater the light intensity, the fewer the number of luminescence.
5. Choose a hair removal device based on light intensity
The product description of the hair removal device will indicate the light intensity in Joules/square centimeter, which is an important indicator for judging the hair removal effect. Generally speaking, at least 5J/cm2 is required to destroy hair follicles and prevent short-term regrowth. Therefore, when girls choose a hair removal device on Taobao, they must at least meet this light intensity standard.
The main difference between home hair removal equipment and hospital hair removal equipment
Nowadays, many girls have grown tired of home hair removal equipment before summer comes, but what I want to tell you is: home hair removal equipment The effect is definitely slightly inferior to the effect brought by hospital hair removal equipment. Because the power of the home hair removal device pursues the safety of use and reduces the amount of energy, the treatment course of girls using the home hair removal device will take longer than the hair removal project in the hospital. In addition, home hair removal devices, like hospital equipment, cannot achieve permanent hair removal and can only maintain the effect for several years after hair removal.
