This historical review traces the evolution of ultraviolet radiation therapy in dermatology, from ancient heliotherapy practices in Egypt and India to modern targeted modalities such as psoralen-ultraviolet A (PUVA) therapy and narrowband ultraviolet B. For millennia, sunlight remained the cornerstone of managing certain cutaneous diseases. This article highlights pivotal innovations, from Finsen's Nobel Prize-winning lamp to contemporary extracorporeal photopheresis, and underscores ultraviolet radiation therapy's enduring role in the treatment of inflammatory and immune-mediated skin diseases.
