Laser hair removal relies on various types of lasers for its treatment, with some of the primary ones being ND Yag Laser, Diode Laser, IPL, and Revlite. These lasers have received approval from the United States Food and Drug Administration (USFDA) for the purpose of hair reduction.
In this procedure, the laser interacts with the pigment found in the hair, generating heat. The process involves directing a concentrated beam of light through the skin to the hair's root. Consequently, the dark hair absorbs enough heat to damage the cells responsible for hair growth. With sufficient intensity, the light can even disable the hair follicle to a degree where it loses its ability to produce hair entirely.
This technology is globally recognized and accepted as a painless method for hair removal, known for its minimal, if any, discernible side effects. Lasers have been utilized in medical procedures for over 15 years, and there have been no reported long-term side effects thus far.
