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.
