808 nm diode laser, it is a laser technology dedicated to permanent epilation. The equipment generates a laser beam of a particular wavelength (808nm) which is able to pass through the skin and be absorbed by the pigments of the hairs inside the hair bulbs, with a consequent increase in temperature and definitive destruction of the germ cells of the same bulb. In this way, the effect of a progressive permanent depilation is obtained through the principle of selective photothermolysis. With the new software update the technology is able to recognize every type of skin and hair up to the light gray color except the white one.
