This is an AI generated summary of the publication Far-UVC Exposure in Patients with Photosensitivity Disorders from the Photobiology Unit, NHS Tayside and the University of Dundee.

This academic article, published in the British Journal of Dermatology, investigates the safety of Far-UVC light (200-230 nm) for individuals with photosensitivity disorders, a group often experiencing adverse skin reactions to various light wavelengths. Far-UVC is known for its germicidal properties and is considered a promising tool for reducing infectious disease transmission. The study, conducted at a photodiagnostic unit in Scotland, involved phototesting 83 patients, including those with diagnosed photosensitivity, using a filtered krypton chloride lamp that emits Far-UVC at 222 nm. Importantly, no visible skin changes were observed in any participant, even at the maximum exposure aligned with international safety guidelines. These findings suggest that Far-UVC, when properly filtered and within recommended exposure limits, is unlikely to harm photosensitive skin, supporting its broader use as a disinfection method in public spaces.
