Ruscinc, Nadia. Bioactive sunscreens containing blueberry (Vaccinium myrtillus L.): physicochemical and funcional characterization. 2018. 103f. (Master Dissertation) – Faculty of Pharmacy Sciences, University of São Paulo, São Paulo, 2018. The deleterious effects caused by ultraviolet radiation (UV) and the significant increase in the diagnosis of skin cancer confirm the need for significant progress in researching effective and safe sunscreen products for effective skin protection. Current formulations associate UV, organic and inorganic filters with limited efficacy that can lead to adverse skin reactions. Vaccinium myrtillus extract (EVM) contains in its composition polyphenols compounds, such as anthocyanins, which have been antioxidant activity. The objective of this study was to evaluate sunscreens containing EVM with broad action spectrum and reduced concentrations of UV filters. Emulsions containing or not EVM and organic (octocrylene and methylene bis-benzotriazolyl tetramethylbutylphenol) and inorganic (titanium dioxide) filters were evaluated and considered stable under pre-defined parameters. The safety of the emulsion was assessed was determined by the in vitro Hen ́s Egg Test – Chorioallantoic Membrane method (HET-CAM) and the antiradical potential of EVM was confirmed by the DPPH• test. The sunscreen formulation containing EVM 5.0% was photoprotective efficacy evaluated in vivo and in vitro and did not show a significant increase in SPF when compared the formulation only with UV filters and no improves skin hydration, according to clinical efficacy assay. The results of the study suggest that even without increase SPF in vivo, the sunscreen formulation containing the extract may show antioxidant activity avoiding damage caused by UV.
