What process does it contains?
Laser hair removal operates on the principle of selective photothermolysis, where a specific wavelength and pulse duration are matched to target a precise object on the skin's surface without harming surrounding tissues. In the case of laser hair removal, the target is the pigment within the hair follicles.
In a laser hair removal session, the laser emits light energy that targets the pigment in the hair. After the melanin absorbs this energy, it travels down to the hair follicle. Once there, it transforms into thermal energy and attaches to the follicle, damaging it and halting further hair growth.
