I read with interest the article by Léauté-Labrèze et al1 titled "Saline Spa Water or Combined Water and UV-B for Psoriasis vs Conventional UV-B" in a recent issue of the ARCHIVES. This is an important article that demonstrates that there is no additional therapeutic effect of bathing to enhance UV-B phototherapy. The authors cited an earlier publication by my colleagues and me,2 mentioning that we "demonstrated that skin sensitivity to UV-B irradiation is increased by bathing in salted water."
