Changes in skin barrier function following single and repeated applications of 4 types of moisturizers: A randomized controlled trial

: Large differences exist in the composition and effect of different moisturizers on skin barrier function. There are a few comparative studies with biometric measurements in this field, specially in normal skin. Here, we compared the effect of 4 types of moisturizers containing humectant (A), occlusive (B), ceramide (C) and hydrating (D) ingredients on healthy skin barrier function, after single application as well as after two weeks of repeated use (table 1).
