The treatments involve twice-a-day light exposure plus daily application of the tar preparation for two to four weeks. In the Ingram method, the drug anthralin is applied to the skin after a tar bath and UV-B treatment. Controlled exposure to certain bands of the light spectrum can ease psoriasis symptoms.
