The correct method of hair removal depends on choosing the right hair removal device. Do you know how to choose the right hair removal device for you? Today, I will share with you the most essential problem, the principle and parameters of the hair removal device!

01  How does the hair removal device achieve hair removal?

Hair removal devices are generally divided into strong pulsed light and laser hair removal methods, the main principles of the two are the same.

The structure of the hair is rich in melanin, and the color is much darker than the surrounding skin. When the strong penetrating light enters the skin, the scattered light acts on the hair follicle and is selectively absorbed by the melanin in the hair follicle. The melanin absorbs light energy and converts it into heat energy, which increases the temperature of the hair follicle to a certain extent. Its structure is irreversibly damaged, hair follicles degenerate and shrink and cannot grow normally, so as to achieve the effect of hair removal.

02  Does hair removal affect perspiration?

Some friends feel that if the hair follicle is damaged, it will affect the perspiration of the skin, but in fact, the tissue responsible for perspiration is the sweat glands in our skin structure. Look at the picture below:

Hair and sweat glands are not the same tissue, so the damage to the hair follicles caused by the hair removal device has almost no effect on the normal perspiration of the skin.

The hair removal device needs to be used consistently in order to affect more hairs in different cycles (growth, anagen, quiescent period). Among them, the hair in the growth period has the most melanin and the highest sensitivity to light, which is the most suitable stage for hair removal

03  How to choose a hair removal device?

Photon Hair Removal Apparatus: A broad spectrum with a wavelength of 610-1200nm. After irradiating the skin, it can effectively penetrate the epidermis to reach the dermis. The melanin in the hair follicles and hair shafts in the dermis is extremely sensitive to this light and selectively absorbs After this light energy, it is also converted into heat energy, which coagulates the dermal papilla, which causes the hair follicles to shrink and the hair shaft to loosen and fall off. 808 (Laser) Hair Removal Apparatus: Single-band laser with a wavelength of 808nm. After irradiating the skin, it can effectively penetrate into the dermis of the skin. The melanin in the hair follicles and hair shafts in the dermis selectively absorbs the laser energy. , It is also transformed into heat energy to heat coagulate the dermal papilla, so that the hair follicle shrinks and the hair shaft loosens and falls off..
