Pharmacokinetic Study of Seresis® in the Skin in Healthy Young Female Volunteers

A Pharmacokinetic Study on the Antioxidant Activity of Seresis® in the Skin: an Open, Uncontrolled, Non-randomized Intra-individual Pilot Trial in Healthy, Young Female Volunteers

Study to evaluate the total antioxidant capacity of Seresis® (with Thiobarbituric acid reactive substances (TBARS) assays)) in the skin; as well as in buccal mucosa cells (BMCs) and in plasma, compared to baseline values; furthermore to detect the quantitative enrichment of individual antioxidant compounds contained in the product and to investigate whether or not some of them accumulate in target tissues such as skin, BMCs and plasma
