Fig. 2. Improvement in skin barrier function indicated by Δ TEWL (%) and Δ SCH (%) in the acidic water bathing group was comparable to that in the wet-wrap dressing group. There were no differences between the two groups in either lesion-free or lesional skin. Results are shown as the mean±standard error of the mean. TEWL: transepidermal water loss, SCH: stratum corneum hydration.
