"Energy-efficient indoor lighting can emit skin-damaging UV light. Researchers examined several compact fluorescent light bulbs and found that nearly all had imperfections in their coating, such as cracks, that allowed UVA and UVC light to leak out. (Both types of light harm skin cells and cause responses associated with cellular aging, but UVC is normally filtered out by the atmosphere.) Within ranges of less than a foot, some bulbs released enough UVC to exceed daily safety limits in 20 minutes. Human skin cells exposed to the lighting showed the same damage as from UV light exposure, says Tatsiana Mironava, a research scientist at the State University of New York at Stony Brook. She advises keeping energy-efficient bulbs at least several feet away or shielding them with a glass cover to filter out more light (not all lamp shades will be sufficient, she adds).\\n\\n\\n\\n\\n\\n\\n\\n#### See Also\\n\\n- [Body News: Fitter Skin](http://www.allure.com/beauty-trends/health/2012/fitter-skin)\\n\\n\\n- [Mood News: Seeing the Light](http://www.allure.com/beauty-trends/health/2007/Seeing_The_Light)\\n\\n\\n- [Scalpel News: Dark Side of Intense Pulsed Light?](http://www.allure.com/beauty-trends/health/2007/Dark_Side_Of_Intense_Pulsed_Light)"^^<http://www.w3.org/2001/XMLSchema#string>
