Ultraviolet (UV) light

Part of the electromagnetic spectrum with a wavelength just below that of visible light. It is damaging to living material, especially eyes and DNA.

UV light

short-wavelength light (180-400nm) occurring naturally in sunlight; long-term chronic exposure or high exposure, especially during childhood, to UV/sunlight can induce potentially neoplastic changes in human skin later in adult life, e.g. basal cell carcinoma, melanoma, Bowen's disease, xeroderma pigmentosum
  • UV-A UV light of wavelength 320-400nm; controlled exposure to UV-A combined with drug therapy (psoralens) is used to treat psoriasis; see photochemotherapy

  • UV-B UV light of wavelength 280-320 nm; UV-B of wavelength 290nm is the most damaging to the skin

  • UV-C UV light of wavelength 180-280 nm

  • UV lamp see Wood's light

Patient discussion about UV light

Q. My husband has psoriasis and the dermatologist suggested that he try the uv light treatment.Anyone try it. some of the side effects may be skin cancer and melanoma's. If so can you please let me know if it actually did help or if not. Thanks a million.

A. uv light treatment procedure is relatively new mod of treatment so here is difficult to build an opinion about it.
Actually there are two main type of treatment relating uv light are in use one is uvb treatment and other one is PUVA (uva light based).
As uvb is the most prominent factor for skin cancer so this treatment is more risky. While PUVA is quite effective treatment and has less side effects.
