Abstract Resonance Raman spectroscopy and multi‐photon tomography were used in vivo to analyse the influence of sun exposure on the cutaneous carotenoids and collagen/elastin fibers. Comparing Berlin (low sun exposure) and Monegasque (high sun exposure) volunteers, it could be demonstrated that extended sun exposure significantly reduces the cutaneous carotenoids and collagen/elastin concentration ( p < 0.05). The tendency towards correlation ( R 2 = 0.41) between the dermal collagen/elastin (SAAID) and carotenoids confirms the important role of antioxidants in the protection against sun‐induced negative effects. The application of sunscreen was shown to be effective, protecting cutaneous carotenoids and collagen/elastin from being damaged subsequent to sun exposure. (© 2014 WILEY‐VCH Verlag GmbH & Co.
