Taking advantage of the accessibility of the skin "in vivo," non-invasive methods were developed about 40 years ago, which have now developed as accurate sources to measure skin properties and structures at the microscopic and macroscopic levels. However, even at the dawn of the twenty-first century, the mechanisms involved in these properties are still only partly understood. As in many domains, including biomedical engineering, numerical modeling has appeared as a complementary key actor for improving our knowledge on skin physiology.

This book gathers, for the first time, chapters describing scientific computing and numerical modeling for a deeper understanding of mechanisms involved in skin physiology. The book is structured around some skin properties and functions, including optical and biomechanical properties, skin barrier function, and homeostasis, covered through several chapters describing either biological or physical models at different scales.
