2023/05/12
Summer is coming, are you still troubled by the hair on your body? The traditional hair removal methods on the market have their own disadvantages, such as waxing and shaving. Although the hair is removed, the hair follicles are still there, which does not meet the fundamental requirements of hair removal. But diode laser hair removal is indeed the most advanced and effective hair removal market.
The same hair removal product is photon hair removal. What is the difference between it and laser hair removal?
Diode laser hair removal is a professional hair removal device, which is comfortable, safe, painless, easy to operate and has better effect. The photon (IPL) machine integrates the functions of hair removal, skin rejuvenation, whitening, freckle removal, acne removal, red bloodshot removal, etc. The SHR mode has fast treatment speed and low pain. Generally speaking, diode laser hair removal is more targeted and more effective.
Why is diode laser hair removal more effective than traditional hair removal? What is the principle?
The basic treatment principle of the diode laser hair removal treatment instrument is selective photothermolysis. The outer hair root sheath in the hair follicle is rich in melanin bodies, which can selectively absorb the energy of the laser. This machine emits 808nm laser, which is easily absorbed by colored hair follicle without damaging epidermal tissue. The energy emitted by the light is absorbed by the hair and the pigment in the hair follicle and converted into heat, thus increasing the temperature of the hair follicle. When the temperature rises to a certain level, the hair follicle will be irreversibly damaged, thus achieving The purpose of permanent hair removal.
Hair growth is divided into growth phase, catagen phase and telogen phase. The three periods repeat themselves. Lasers are only effective for hair in the growth phase, and have no effect on hair in the catagen and telogen phases. Generally speaking, the hair in the growth period accounts for 1/5 to 1/3, so laser or photon treatment must be performed about 5 times in a row to completely remove the hair. And diode laser hair removal adopts three-band treatment principle: 755nm is aimed at shallow hair and light-colored sparse hair, 808-810nm is suitable for most skin colors and most hairs, and 1064nm has strong penetration, which is more suitable for dark skin and deep skin Hair treatment.
