Lasers are devices that produce beams of specific wavelengths. The effect of lasers on the skin occurs through structures called chromophores in the skin. Devices used for laser epilation either see and burn the melanin pigment in the hair root and burn the hair root, or they target the vessels in the hair root and disrupt the nutrition of the hair and indirectly act by burning the hair with the heat of the laser light.
Depending on the wavelengths, the depth at which the lasers can advance in the skin differs.
Lasers used for hair removal, Alexandrite laser, Diode laser, Nd-YAG laser and IPL systems that do not actually fall into the laser class but perform laser-like photothermolysis are used.
The devices used for laser epilation work best on white skin, dark and thick hairs, the success rate is lower in fine hairs, and they do not affect white hairs. The success of laser epilation may vary depending on the location of the hairs due to their structure. While the success rate increases in the armpit, genital area and dark lower leg hair, the success rate is lower in the facial mustache area and thin upper legs and arms.
The expected success rate with laser hair removal is around 80%. Although it weakens some hairs, it cannot completely destroy it. In such cases, picking up the rest with needle epilation increases satisfaction.
