Figure 2: Stratum corneum (SC) moisture retention following application of mineral oil emollient. In (a), transepidermal water loss (TEWL) from the SC is shown under ambient temperature, humidity, and pressure. In (b), TEWL is reduced following emollient application. Oils in the emollient create a semiocclusive layer. The reduction in water evaporation leads to greater water retention in the SC.
