A new approach for an estimation of the equilibrium stratum corneum water content

Abstract

The estimated water content is a bit lower than what can be expected to be realistic. A calibration against ambient RH is most probably needed if our method is to be applied over a broad range of values of the RH in the ambient air.

Skin response to sustained loading: A clinical explorative study

“…Because skin temperature influences water evaporation we statistically adjusted the TEWL to 30 C. Although a generally accepted conversion formula does not exist [44] the approach introduced by Mathias et al [35] was chosen, because it is the most established one in the literature [45,46]. After adjustment we still observed a substantial TEWL increase at the heels whereas the TEWL seemed not to change at the sacral skin.…”

Endoscopic-Guided Measurement of Mucosal Admittance can Discriminate Gastroesophageal Reflux Disease from Functional Heartburn

“…In the field of medical engineering, it is widely known that the low-frequency current mostly flows within the extracellular fluid, whereas the high-frequency current flows through intracellular and extracellular spaces; this property is found in all biological tissues. 28, 29, 30 In several functional studies, DIS has been recognized as a marker of impaired transepithelial permeability. 31, 32 Thus, when evaluating extracellular fluid volume, using a low-frequency current may be more useful to estimate DIS and transepithelial permeability.…”

Effects of water nanodroplets on skin moisture and viscoelasticity during air‐conditioning

“…, indicating that TEWL on the cheek decreased from the time point 0 h to 3 h, and significantly at 6 h ( P < 0.05), when the temperature was kept at 24–25°C with 10% relative humidity. TEWL is the amount of diffused water from the surface of SC, which depends on the water content of skin and ambient vapor . Water is continuously supplied from the deep layer of the skin toward the surface of SC to maintain the moisture level.…”
