The Diode Laser is very effective for darker skin as the laser features a longer wavelength, therefore able to hit a wider range of skin types. It provides safer and deeper penetration into the skin layer, thus having fast repetition rates. It also covers large areas and allows for fast treatment of larger body areas. It is painless, because it is cold integrated without damage to the surrounding skin. The diode laser hair removal is suited for light, medium and darker skin types.
