How to choose a cost-effective home hair removal device
Today I would like to talk about how to choose a cost-effective home hair removal device. First of all, we need to have some knowledge about the hair removal device. The hair removal device is divided into home IPL (Intense Pulsed Light) type and laser Type. Their principle of both hair removal is same. "Selective photopyrolysis effect" is simply "using hair follicle melanin to absorb light energy and then heating the hair follicle, thereby destroying the hair follicle to achieve the purpose of hair removal." At present, the most hair removal devices on the market are IPL. The Laser Hair Removal Devices are generally used in beauty salons and hospitals.
Generally, for home hair removal device we just need to choose the IPL type. The energy of laser type is too high to ensure safety for home. The most important specification of IPL hair removal device is the wavelength and energy.
Wavelength: The longer the wavelength is, the penetration to the skin is stronger, the hair removal effect is better, and the less damage to the skin.
Principle: Different wavelengths have different penetrability in skin tissue. The longer the wavelength is, the penetrability of light is better. The wavelength energy can pass through the skin surface to the root of the hair follicle, and then the light in the hair follicle will be absorbed and transformed. Thereby, it can destroy the hair follicle tissue. The heat can burn the hair root in the growth phase, and the light energy will not damage the surrounding tissues while working on the hair follicle, so the safety performance is also very high.
Energy: The higher the energy is, the more heat to the hair follicles, and of course the hair removal effect will be better.
Principle: The energy of the home IPL hair removal device is not particularly high, so don’t need to worry about the energy being too high and hurt the skin, while the energy of the general home hair removal device only needs to reach about 4J/ cm² to achieve the effect of hair removal.
In terms of effects, every hair removal device on the market has more or less effect. Because of different technologies and hair removal cycle, the hair removal effect and hair removal experience are not the same. You can make the choice according to your needs.
