Diode Laser Three Wavelength Hair Removal Machine

Melanin is rich in hair follicle epithelium, hair papilla, and hair cortex. Melanin selectively absorbs laser energy and the produced energy immediately forms local high temperature, which damages hair follicles and hair shaft, hinders and terminates hair growth. Laser energy tends to be easily absorbed by melanin in hair follicle and hemoglobin in dermal papilla nutrient vessels, and then producing photothermal effects. When the temperature in hair follicles rises to some certain degree, thermal expansion happened in hair follicle fractures melanin cells and be pushed out of hair pores by steams. At the same time, dermal papilla nutrient vessels are damaged because of hemoglobin solidification. Under above dual functions, effective hair removal will be achieved.
