Irritation potential of bath and shower oils before and after use: a double-blind randomized study

Abstract

The results showed large differences between the products in irritant potential. Some did not irritate skin more than water, whereas others demonstrated considerably damaging effects. Moreover, the study proved the presence of barrier-impairing residues on the skin after rinsing with water. Thus, instead of protecting the skin, some formulations may induce subclinical injuries and delay skin barrier function recovery with prolonged risk for patients with eczema.
