Abstract

The cover illustrates the measurement of human skin carotenoid levels based on pressure mediated reflection spectroscopy. Carotenoids have a widespread distribution in fruits and vegetables, are taken up through the diet, and play an important role in tissue health through their function as antioxidants. Their characteristic absorption in the blue/green spectral range can be quantified in human tissue such as the thumb and tracked upon dietary supplementation. (Picture: I. V. Ermakov and W.
