IPL stands for intense pulsed light, and it is a form of light therapy, similar to laser, it is used for various dermatological procedures including permanent hair removal. As with all light based hair removal treatments, our IPL handset works by emitting a wavelength which targets pigment in the hair. As the light is absorbed by the pigment in the hair it turns to heat which then kills the hair growth cells. Hair will grow back more sparse and slower after each treatment, reducing hair growth permanently overtime.
