Kobe University and Ushio Prove 222 nm Far UV-C Light Reduces Bacterial Counts and Causes No Damage on Human Skin

Ushio and a research group from Kobe University Graduate School of Medicine have completed a study proven that irradiation of filtered 222 nm UV-C light on human skin reduces bacterial counts while causing no injury to the skin. This is the first study on the safety of 222 nm far UVC light conducted on humans. The research paper regarding this study is published on PLOS ONE, titled “Exploratory clinical trial on the safety and bactericidal effect of 222-nm ultraviolet C irradiation in healthy humans.” (Image: Ushio) In this study, Ushio’s C...
