The excimer laser—recently approved by the Food and Drug Administration (FDA) for treating chronic, localized psoriasis plaques—emits a high-intensity beam of ultraviolet light B (UVB).

The excimer laser can target select areas of the skin affected by mild to moderate psoriasis, and research indicates it is a particularly effective treatment for scalp psoriasis. Researchers at the University of Utah, for example, reported in The Journal of Drugs in Dermatology that in a small series of patients, laser treatment, combined with a topical steroid, cleared scalp psoriasis that resisted other treatment.

Individual response to the treatment varies. It can take an average of four to 10 sessions to see results, depending on the particular case of psoriasis. It is recommended that patients receive two treatments per week, with a minimum of 48 hours between treatments.
