Newest 755nm 808nm 1064nm 3 Wavelength Diode Laser Hair Removal MachineThe principle of laser hair remove is selective thermokinetics. which is select wavelength only acts on melanin but not on normal skin tissue, and the selected pulse width only acts on melanin in hair follicle but not on melanin in skin basal layer.) There are abundant melanin in hair follicle and hair stem. Melanin is distributed between the cells of hair bulb matrix, and can also transfer to the structure of hair stem (such as medulla, cortex and
