Information

Laser hair removal is the process of hair removal by means of exposure to pulses of laser light that destroy the hair follicle. It had been performed experimentally for about twenty years before becoming commercially available in 1995 and 1996. One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998.Laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment. Many reviews of laser hair removal methods, safety, and efficacy have been published in the dermatology literature.

R. Rox Anderson and Melanie Grossman discovered that it was possible to selectively target a specific chromophore with a laser to partially damage basal stem cells inside the hair follicles. This method proved to be successful, and was first applied in 1996. In 1997, the United States Food and Drug Administration approved this tactic of hair removal. As this technology continued to be researched, laser hair removal became more effective and efficient; thus, it is now a common method in removing hair for long periods of time.

Beijing superlaser company produces 808nm wavelength Diode laser machine, which penetrates into the dermis, and the laser is absorbed by the targeted melanin in the hair follicles. This will form enough thermal energy to destroy the targeted follicular epithelium because of the laser-induced photothermal effect. In contrast, the surrounding skin tissue is spared due to lack of mela nin. This way, the surrounding skin remains intact, while the hair follicles are selectively affected, which leads to non-invasive permanent hair reduction.
