Abstract: Active ingredients of plant origin such as polyphenols and phenolic acids are enjoying increased acceptance in both the food and cosmetics industries. Their often excellent antioxidant properties are determined by in vitro assays. To develop an effective skin care formulation, their penetration ability and bioavailability has to be investigated as well. Both depend on molecular size, but also on the molecules’ balance of lipo- and hydrophilicity. In this paper, the antioxidant activity of individual coffee fractions (roasted and unroasted) is compared by means of in vitro antioxidant assays, and the influence of the formulation on skin penetration of the antioxidant active is examined by in vivo Raman spectroscopy.
