June 16,2022
The principle of hair removal at home is the same as that of beauty salons, and it is safe to use. You can easily remove hair at home. So what parameters do you need to look at when buying a hair removal device?
1. Wavelength
Different wavelengths have different effects on human skin; the wavelength suitable for human hair removal is 640nm-1200nm, but this wavelength range only has the function of hair removal, not skin rejuvenation, and light in the range of 510nm-640nm can also be used Absorbed by the skin, it can make the skin produce new collagen, and it also has functions such as blemish reduction and wrinkle removal.
The photon skin rejuvenation instruments on the market basically use this wavelength, and the wavelength below 400nm is the ultraviolet light that we can't avoid. Directly irradiating the skin will accelerate the aging of the skin.
2. Energy
The greater the output energy of the hair removal device, the more obvious the hair removal effect. The energy density of large hair removal devices used in beauty salons is 10-30J; the energy of household hair removal devices is generally 2-7J, and some can reach 4-6J. The effect is guaranteed.
3. Ice feeling
Some friends may have found that many domestic brands of hair removal devices have ice-sensing functions, but foreign brands do not, because IPL hair removal devices are originated from Europe and the United States, because Europeans and Americans have white skin, and the epidermis absorbs less light during hair removal, resulting in The burning sensation is less, and Asians have yellow skin and more pigmentation, and it is easy to feel pain during hair removal. The ice-sensing function can quickly cool the skin surface and improve the hair removal experience.
4. Light-emitting area
The larger the light-emitting area of the epilator, the larger the coverage of the skin, which can reduce the time of hair removal and improve the efficiency of hair removal.
