A methods is described which allows the humidity measurement of the horny layer of the human skin. The method is based on the correlation between the direct current conduction at 3.0 V and the gravimetrically analyzed humidity of a homogenous skin model. The validity of this model is mainly limited by the nonhomogenous distribution of humidity in the stratum corneum. This method is applied to healthy human skin to find out the dynamic response of the skin to moisturization by water bath. It is a surprising result that 15 min after the bath the horny layer is dryer than before starting the experiment. The kinetic of the humidity change from the moisturization state to the equilibrium state is followed, after a fast initial phase, by a normal exponential decay, which is used as a proof for the applicability of the correlation between the electric conductivity and the humidity of the model for the determination of the overall humidity of the human horny layer.
本文描述了一种用于测量人体皮肤角质层湿度的方法。该方法基于3.0V直流电传导与均质皮肤模型重量分析湿度之间的相关性。该模型的有效性主要受角质层湿度非均匀分布的限制。此方法应用于健康人体皮肤，以探究皮肤对水浴保湿的动态反应。令人惊讶的是，沐浴后15分钟角质层比实验开始前更干燥。在快速初始阶段之后，从保湿状态到平衡状态的湿度变化动力学遵循正常的指数衰减，这被用作电导率与模型湿度之间的相关性适用于测定人体角质层总体湿度的证据。
