Mechanical features of and damages to the outer skin, such as pliability, stretchability, stickiness while wet, and chapping seem to depend, at least partly, on the water content of the stratum corneum, or, rather, the barrier layers. Statements on the behavior of callus cannot be immediately related to those regarding the barrier layers. The water content of the barriers depends on the local relative humidity. There seem to be at least two barriers. Their variable water vapor diffusion resistances, the external milieu and the active transfer processes below the barrier control the relative humidity of the barrier layers. Author
