IPL (intense pulsed light) works by targeting the dark pigment around the hair follicle in order to damage it sufficiently to cause the hair to fall out and inhibit its ability to re-grow. As the light is absorbed by the melanin, it produces heat energy, which causes the damage. The growing hair will fall out between one and two weeks following treatment.
Objective studies show up to 92% hair reduction in as little as 3 treatments. The first 4 treatments must be carried out every 2 weeks, after which you should already be able to see the desired results. To maintain your results, simply touch up every 4 weeks. After just 8 touch up treatments you can enjoy hair-free smooth skin for 6 months.
