The advantage of laser hair removal is that it is thorough. Laser can penetrate deep dermis and subcutaneous adipose tissue, act on deep hair follicles in different parts, and effectively remove deep hair in any part of human body. Therefore, it is very suitable for beauty lovers to choose whole body hair removal.
Using melanin in hair follicle to absorb laser with a specific wavelength of 800nm to produce photothermal effect, destroy hair growth cells, fundamentally stop hair growth and achieve the effect of permanent hair removal. Laser hair removal uses the principle of "selective photothermal effect" of laser. The hair follicle is directly irradiated through the epidermis with a laser tuned to a specific wavelength. Melanin in hair follicle and hair shaft selectively absorbs light energy, which leads to hair follicle necrosis and hair no longer grows.
The laser pulse time required for the best hair removal effect is related to the thickness of hair. The thicker the hair, the longer the laser action time. The laser pulse time of semiconductor laser is from 5 seconds to 100 milliseconds, which can effectively protect the epidermis from thermal damage while obtaining ideal hair removal effect.
