Modern light-based technologies such as IPL (intense pulsed light) are the ability to get rid of unwanted hair permanently. The IPL technology uses a broadband pulsed light source. Light waves of different lengths affect the area of the skin and the hair growing on it. When the light pulses reach the hair follicles, they interact with the melanin pigment, heating it up. The heat from the light pulse has a destructive effect on the cells of the hair roots and prevents their renewal. That is, the flashes of light destroy the "growth center" of the hair - the root. The effect is permanent - after 4-5 procedures, new hair does not grow.
