Ushio Inc. and a research group led by Dr. Ryosuke Kuroda, Chairman and Professor of the Department of Orthopaedic Surgery, Kobe University Graduate School of Medicine, have completed a research study that shows that irradiation of filtered 222nm UV-C light on human skin reduces bacterial counts while causing no injury. This is the first study on the safety of 222nm far UV-C light conducted on humans.
