A variety of lasers and IPL systems are available and are the most effective options for long-term hair reduction. The mechanism of action of these systems is the targeting melanin in the hair shaft, follicular epithelium, and hair matrix by emitting light with wavelengths ranging from 600 to 1200 nanometers (nm), because those wavelengths are selectively absorbed by melanin.

Diode Laser (810 nm) - Penetrates deeper, delivers better fluence, less epidermal damage, safer in darker skin (skin types I-V)
Neodymium-doped Yttrium-Aluminium-Garnet (Nd: YAG) Laser (1064 nm) : Better penetration, less epidermal damage, relatively less melanin absorption (skin types I-VI)
Intense Pulse Light (IPL) or Broadband Light (BBL) (500-1200 nm) - High-intensity pulses of polychromatic, non-coherent light are delivered by a flash-lamp; various filters allow the narrowing of the emitted wavelength band, can be used on darker skin, larger areas can be covered due to its larger spot size, less expensive than a true laser but not as effective.
