What is the use of light produced by lasers to destroy the hair bulb and follicle for hair removal called?

The use of light produced by lasers to destroy the hair bulb and follicle for hair removal is referred to as photothermolysis. This method utilizes the principle of selective photothermolysis, where specific wavelengths of light are absorbed by the melanin in hair follicles. This absorption generates heat that effectively damages the hair bulb and surrounding follicular tissue without harming the surrounding skin.

Photothermolysis is specifically designed to target the pigment in the hair, making it an effective technique for hair removal, especially in individuals with darker hair against lighter skin. The precision with which lasers can focus on the desired tissue while minimizing damage to adjacent areas is a distinguishing feature of this method. This principle not only enhances effectiveness but also improves safety and reduces potential side effects associated with hair removal procedures.
