Diode lasers use semiconductor technology that produces a coherent light projection in the visible to infrared range. They use a light beam with a narrow spectrum to target specific chromophores in the skin. Compared to other laser systems, such as the Ruby and the Alexandrite, the 800 nm diode laser wavelength offers the deepest penetration levels and superior melanin absorption. These unique characteristics make the diode laser the most suitable technology for laser hair removal, enabling safe and effective treatment of all skin types.
