Postquam DIODE LASER HAIR REMOVER

The diode laser has a longer wavelength than the Alexandrite and Ruby lasers. (Ruby laser is a red-colored beam of light used to strike the dark melanin, which is a biological pigment, present in the hair follicles.) Hence, diode is able to penetratedeeper into the skin, allowing treatment on dark-skinned people, unlike the other two lasers.
