A diode laser uses a light beam with a narrow spectrum to target specific chromophores in the skin. Compared to other laser systems such as the Ruby and Alexandrite, the 800nm 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 in darker skin patients and performs well on coarser hair. Alexandrite operates on a shorter wavelength, which is more effective for lighter skin types.

How Does A Diode Laser Work?

​

Diode lasers use the principle of selective photothermolysis (abbreviated SPTL) to target specific chromophores in the skin, usually melanin or blood.  The lasers damage the chromophores by selectively heating them while leaving surrounding tissue unharmed.  When treating unwanted hair, for example, the melanin in the hair follicles is targeted and damaged which results in the disruption of hair growth and regeneration.  A diode laser can be complemented by cooling technology, or other pain reducing methods which improve treatment efficacy and patient comfort.
