How does hair removal with the Cutera Nd YAG Laser work?
Laser energy passes through the skin to the hair follicle, where the pigment in the hair follicle absorbs the energy, causing selective damage to the hair root, without damaging the surface of the skin. The laser is pulsed, or turned on, for only a fraction of a second. A pulse duration is selected so that laser energy is absorbed by the hair follicle without transferring excess heat to the surrounding skin. Some hair follicles fall out immediately, while others take 2-3 weeks to shed.
