Depth profiling of stratum corneum hydration and lipids in vivo: Comparison between short wave infrared spectroscopic and biophysical measurements

摘要

We present a short-wave infrared spectroscopic method for quantitative depth profiling of water and lipids content in the stratum corneum after tape stripping. The results show that the SC is a non-uniform membrane, characterized by gradients in the properties of lipid and water content.
