IPL uses light pulses to remove unwanted hair growth on the body, dampen hair regrowth and counteract irritated skin. They are available with battery operation, mains operation, included charging unit, display and mobile control. Also look at the life of the lamp, the strength of the light fluence and how large an area it covers. Models with a skin sensor identify hair that cannot be treated. Products in this category are also called Intense Pulsed Light.
