Water Content of Stratum Corneum 'In Vivo'.
Abstract
The authors using a 4-point microelectrode method for studying the relationship between electrical resistivity, water content, electrolyte levels, and water binding in stratum corneum. Resistivity is measured with a microcircuit skin surface probe printed onto a glass substrate. A constant current source drives the outer two electrodes at 1 Hz; the potential drop is measured across the inner two electrodes. The device is capable of obtaining accurate surface resistance measurements on two layer materials when the first layer is between 0.1 - 0.4 mm thick; on plantar and palmar skin this corresponds to the stratum corneum. Samples of plantar skin have been tested during standardized desorption procedures.
