title: Time series trend of the water content on the different human anatomical sites using single frequency-susceptance measuring method.
abstract: The water content of stratum corneum (SC) has been reported to vary depending on the anatomical sites. Each anatomical site respectively have their own proper water content of SC which reflects the status of skin health. Also, this anatomical region can be divided into relatively wet and dry area according to the degree of the water content of SC. In this study, we tried to investigate time series trend of the water content. Skin hydration was measured on the different anatomical sites for the first four seconds using single frequency-susceptance measuring method. It is observed that the slope of the graph for the water content during the first four seconds is different depending on the anatomical sites and can be divided into two groups by the degree of the slope. These grouped areas are well aligned with traditional wet and dry area. It is presumed that the difference of the gradient could be caused by the thickness of SC. In this study, the different gradient of time series trend of water content of SC on different anatomical sites was found, and it could be conveniently used to distinguish the wet and dry area of the skin.
