Study of three complementary techniques for measuring cutaneous hydration in vivo in human subjects: NMR spectroscopy, transient thermal transfer and corneometry – application to xerotic skin and cosmetics

Background/aims: The aim of this study was to determine the capability and the analytical quality of three different in vivo, non‐invasive, quantitative methods for measuring skin hydration: two innovative methods that have been used for more than eight years – nuclear magnetic resonance spectroscopy (NMR‐S) and transient thermal transfer (TTT) – and the more widely used and conventional corneometry.
