The laser that produces a larger beam of highly concentrated light. The light emitted is well absorbed by the pigment located in the hair follicles. During the procedure, the laser pulses for a fraction of a second, allowing the hair to absorb the light and heat up. As it heats up, the hair shaft and bulb are damaged which significantly impedes its ability to re-grow. And with the large spot size, the process treats numerous hair follicles simultaneously, making the treatment much faster than traditional laser hair removal alternatives.  Laser hair removal requires multiple treatments. This is because the laser works best when hairs are in an early growth stage (referred to as anagen), and all the hairs are not in this phase at the same time.

During the initial stages, you will feel a light stinging sensation, which indicates that the laser has been activated. Then a series of impulses are produced and may cause a slight burning sensation and some prickling. Your technician may apply a topical anaesthetic to the body area under treatment, in order to minimize the discomfort. But most people do not need the anaesthetic. Some people have said that the feeling is like that of a rubber band snapping against the skin.
