Spring is a good season for hair removal. Of course, there are many choices for hair removal, among which laser hair removal is a common way. Photon hair removal is a kind of laser hair removal.
Laser hair removal is generally based on the principle of selective thermodynamics and the latest laser technology. The light beam emitted by the laser machine will penetrate the surface of the skin and finally be absorbed by the hair follicle. Through the selective absorption of laser energy, the hair follicle will be damaged and can not regenerate long hair without damaging the surrounding tissues. The process of laser hair removal is simple and fast. Generally, no scar is left after treatment.
According to laser beauty experts, laser therapy uses a series of laser pulses, which will be accompanied by a little tingling or slight burning feeling. During treatment, some beauty seekers may have temporary redness or swelling, or even mild skin pruritus. The redness and swelling subside and the skin returns to normal a few hours after treatment. The laser will not damage the skin, so there is no need to do any treatment. There is little discomfort after treatment, which does not affect normal life and work. The time required for treating different parts is also different. The time for treating the beard part of the lip is 5 to 10 minutes, the time for treating the hair of both lower legs is 30 to 40 minutes, and the time for treating the hair of both lower limbs is about 90 minutes.
Laser can remove hair by destroying hair follicles, and hair follicle growth can be divided into growth period, resting period and degenerative period. In the growth period, the hair follicle has the most melanin and the strongest absorption of the light emitted by the laser, which has become the best target of the laser hair removal machine. The more melanin, the more clear, the higher the hit rate, and the greater the damage to hair follicles. Laser has little effect on degenerative hair follicles and no effect on resting hair follicles. Therefore, some hair may regenerate after hair removal, but the newborn hair will become thinner and less obvious. The effect varies from person to person. Some people grow hair after 6 months, but others will not regenerate until 2 years later. Because some hair follicles are in the resting and degenerative stage at any time, multiple treatments are needed to achieve the effect of destroying hair follicles.
