Résumé
The antioxidant status of the skin shows constant alterations depending on nutrition and other lifestyle factors. Carotenoids can serve as marker substances for the antioxidant status of the epidermis in vivo. The carotenoid concentration of 2 homemade green smoothies and a commercial green smoothie, all containing fruits and vegetables, was assessed by resonance Raman spectroscopy. Furthermore, a pilot study was conducted to investigate changes of the cutaneous carotenoid concentration of 20 healthy volunteers under the daily intake of either a homemade smoothie or the commercial smoothie in vivo using reflectance spectroscopy. We hypothesized that higher carotenoid concentrations in the homemade smoothies compared to those of the commercial one would lead to a faster increase of the cutaneous carotenoid concentration in healthy volunteers. The measurements of the homemade smoothies showed notably higher initial carotenoid concentrations (7.6 ±0.8)*10
