Intense Pulsed Light (IPL) is coherent light that targets extra blood vessels present on the skin and eyelids. This reduces the level of pro-inflammatory mediators as well as bacteria and Demodex mites, thus effectively removing major sources of inflammation around the eyes. IPL also improves the consistency of the meibomian glands and rejuvenates the glands that have begun to atrophy. It has also demonstrated beneficial effects on the ocular surface nerves.
