The process is performed using laser beams, where both the wavelength and the duration of the beams, which are directed to the hair follicles, are selected only to stop them from producing hair without affecting the surrounding tissue.
This is done very carefully to get the best results and less damage to the skin tissue. For example, the dark skin of the skin pulls the laser rays more than light skin or blonde, so it is preferable to use a longer wavelength of dark skin for light skin.
Since it has been defined as reducing the number of capillaries in the body over a long period of treatment, in fact many patients have suffered full hair growth in areas that have been treated in the years following the last treatment session. This means that although laser therapy with these devices will reduce the total number of body hair, it will not result in the removal of all hair permanently.
