An older form of light treatment for psoriasis may be better than a newer, safer version, say researchers.

While ultraviolet B light (UVB) has proved to be a convenient and somewhat safe form of treatment for psoriasis patients, it turns out that an older type of light therapy, ultraviolet A (UVA), is more effective in treating the symptoms of psoriasis.

Light therapy is a common treatment for psoriasis. However, UVA requires the use of psoralen, an oral drug, in a treatment called PUVA. Psoralen causes nausea, requires eye protection after treatment and cannot be used in patients who are pregnant or taking other drugs. Additionally, prolonged use of UVA has been shown to increase the risk of some types of skin cancer.

Because of these safety issues, physicians prefer UVB over UVA. However, until now, there has never been a study to determine if they were equally effective.
