Ultraviolet light therapy or ultraviolet phototherapy is a treatment for psoriasis, atopic skin disorder, vitiligo and other skin diseases. There are two main treatments: UVB that is the most common, and PUVA.
PUVA (psoralen and UVA) is an ultraviolet light therapy treatment for skin diseases: vitiligo, eczema, psoriasis, graft-versus-host disease, mycosis fungoides, large plaque parapsoriasis, and cutaneous T-cell lymphoma, using the sensitizing effects of the drug psoralen.
UV-B treatments for skin conditions such as psoriasis, vitiligo, and atopic dermatitis are administered in very low doses, often lasting only a few minutes or less than a minute when using lamps emitting 290-300 nanometer light. This low dosage does not significantly increase the risk of skin cancer, making UV-B phototherapy a safe treatment ...
Phototherapy is an effective treatment because it forces skin cells to manufacture melanin to protect the body from UV damage. Prescribed treatment is generally 3 times a week in a clinic or daily at home. About 1 month usually results in re-pigmentation in the face and neck, and 2–4 months in the hands and legs.
Treatment costs are for 45ml (5ml three times a day for three days). Dividing the median unit local procurement price for each medicine, by the median unit price from international suppliers in the guide, produces the Median Price Ratio (MPR). An MPR of 2 means the local health service is paying twice as much as the international reference price.
Artificial UV light sources from tanning units and phototherapy treatment units can also trigger PLE. About three-quarters of patients acquire PLE after UV-A exposure only, one-tenth after UV-B exposure only, and the rest after a combination of UV-A and UV-B exposure. [6] People vary in the amount of sun exposure needed to trigger the rash. [15]
In the late nineteenth century. Finsen successfully demonstrated phototherapy by employing heat-filtered light from a carbon-arc lamp (the "Finsen lamp") in the treatment of a tubercular condition of the skin known as lupus vulgaris, for which he won the 1903 Nobel Prize in Physiology or Medicine.
