How is IPL/LASER technology used to safely remove unwanted hair?

The IPL/LASER machine emits a gentle beam of light that passes through the skin and targets the pigment in the hair follicles. The pigmentation that exists in hair attracts the light and causes it to convert to heat, which cauterizes the base of the hair follicle. The hair follicle dies and should never again produce a hair. The light does not harm pores or the structures of the surrounding skin.
