## Abstract A model for the hydration behavior of human stratum corneum has been developed from measurements on __in vitro__ samples isolated in a manner which minimized tissue treatment and trauma. Water sorption/desorption rate measurements as a function of water activity, temperature, and tissue

At low water activities, stratum corneum (SC) water sorption resembles that in other keratinized tissues (i.e., wool and horn), whereas at high water activities, it resembles that in polymeric hydrogels. We propose that the concentration-dependent water diffusivity observed in these other systems ap
Urea, as a final product of protein metabolism, is a physiological substance in the human organism. The elimination of urea in humans amounts to 30 g per day; the amount in urine is of the order of 2% and in the blood 250 mg per ml. The urea content of human skin is about 1%. Urea, as one of the na
