<unk>  is the use of<unk> <unk>  of non-coherent light over a range of wavelengths from 500 nm to 1200 nm. Xenon flashlamps produce high output bursts of broad spectrum. Cooling is used to protect the skin in contact with the device. Regulations governing<unk>  vary by jurisdiction. A distinction is sometimes made between beauty-grade and medical-grade machines, mainly to get around regulations. The first FDA approval of<unk>  was for telangiectasias in 1995. Use quickly spread to a variety of medical and cosmetic settings. Treatment is generally safe and effective, but complications can occur, such as hyperpigmentation. The polychromatic light can reach multiple chromophores in human skin: mainly hemoglobin, water, and melanin. This results in selective photothermolysis of blood vessels, pigmented cells, or hair follicles.
