Light is absorbed by the melanin (the pigment in the hair follicle). The light energy heats the pigment and effectively destroys the cells in the hair follicle which are responsible for hair growth, without damaging the surrounding cell.
The laser guide is placed on the skin and a short pulse of light is released, which targets many follicles simultaneously. The applicator is then moved to the neighbouring area of the skin and the process is repeated until the entire area is covered.
