title: Constant low-dose ultraviolet light therapy for psoriasis.
abstract: In a bilateral comparison study, symmetric plaques of psoriasis were used to compare the effects of a constant low dose (3 minutes, 30 seconds) of ultraviolet light therapy to the standard increasing ultraviolet light dose. The low constant dose of ultraviolet light was as efficacious in clearing psoriasis lesions as the higher increasing dose.
