Biomechanics of the Barrier Function of Human Stratum Corneum

  • Chapter
  • First Online:
Treatment of Dry Skin Syndrome

Abstract

In this chapter, we review new approaches to characterize and model the fundamental biomechanics of human stratum corneum (SC) and skin damage processes. We describe how the drying stresses that develop in SC provide a mechanical driving force for dry skin damage such as chapping and cracking. We review techniques to quantitatively characterize these stresses after environmental conditioning and application of moisturizing and damaging treatments. We discuss the critical effect of water content on the mechanical properties of SC, and demonstrate the relationship between the SC drying stress and water in the drying environment. Finally, using our biomechanical model, we demonstrate how damaging treatments enhance and moisturizing treatments alleviate the propensity for dry skin damage.
