Water in human stratum corneum plays a key role in its functionalities and cosmetic properties. Therefore, an understanding of water content, water concentration depth profile and free water migration within the stratum corneum is fundamental to skin research. In this paper, we present a theoretical study on water concentration depth profiles and water flux profiles within human stratum corneum under various initial and boundary conditions. Results for steady-state and dynamic water concentration depth profiles are presented, together with in-vivo measurements using opto-thermal radiometry and condenser-chamber TEWL.
