These bursts of light are changed into heat energy, eventually damaging or killing the root of the hair shaft and follicle so it stops growing. Filters on the IPL machines are used to ensure that the light can be precisely targeted on the intended hairs as accurately as lasers, though, as the IPL equipment head is often bigger you can get quicker results.
