Some skin conditions, like eczema and psoriasis, can be treated with ultraviolet (UV) light. It is generally used to manage symptoms rather than as a cure and can be used with other treatment options such as medicines and moisturisers.

Light therapy has a long history and it really developed in the late 1800s and early 1900s as a popular treatment for a wide range of conditions. Carried out with both natural sunlight and artificial light, UV rays were thought to be most beneficial. Their use was found to disinfect wounds and boost vitamin D production essential for bone growth. Niels Ryberg Finsen popularised light therapy and won the Nobel prize in 1903 for his work using it to treat the lesions left by smallpox and tuberculosis of the skin. However, its uses and benefits were widely discussed and sometimes disputed in the medical and popular press.
