title: Comparison of different instruments for measuring stratum corneum moisture content.
abstract: Synopsis Stratum corneum moisturization was measured by two instruments simultaneously on the same subjects at different body sites. One instrument is based on the 1 GH(z) focused mirowave dielectric measurement; the other instrument measures impedance at 16 Hz. A linear relationship r = 0.86 was observed between the measurements by the two above-mentioned instruments. The 1 GHz focused microwave measurement is more accurate in measuring water concentration in the stratum corneum, especially in the upper layers relevant to "moisturization"; it is, however, an expensive research instrument. The low frequency impedance measurement involves a much simpler, cheaper and portable instrument which can be used routinely to evaluate 'moisturization' for the purpose of skin classification under field conditions.
