How Can The Laser Remove The Hair ?

The laser emits an invisible light which penetrates the skin without damaging it; it is then absorbed by the pigments of the pilous follicle. The laser light selectively absorbed by the follicle damages its functions and impairs its ability to fabricate hair. At the level of the pilous follicle, the laser light absorbed by the pigments is then transformed into heat which damages the hair but not the surrounding skin.
