A randomized, double-blind, negatively controlled pilot study to determine whether the use of emollients or calcipotriol alters the sensitivity of the skin to ultraviolet radiation during phototherapy with narrowband ultraviolet B

摘要

Background There is contradictory evidence suggesting that emollients increase, decrease or have no effect on minimal erythema dose (MED) or minimal phototoxic dose values prior to phototherapy. Few studies have looked at the in vivo use of emollients or calcipotriol prior to narrowband ultraviolet (UV) B (NB-UVB) treatment.
