C. Sauvignon) through the evaluation of one extract (grape pomace extract, GPE) and two fractions (one chloroform, GPE-CHF; one ethyl acetate, GPE-EAF). The samples were characterized analytically by liquid chromatography (HPLC) using a NIH 3T3 fibroblast cell culture to verify a cytosafety profile in normal and stressful environment (presence of H2O2), and by using it in a sunscreen system to observe improvements in the in vitro efficacy by diffuse reflectance spectrophotometry with an integrating sphere. The HPLC results for GPE-EAF and GPE-CHF samples with the best profile of syringic and p-coumaric acids, quercetin, and trans-resveratrol were used in the further assays. GPE-EAF and GPE-CHF, both at 30.00 \u00b5g\/mL, maintained the cell viability in the absence of H2O2 (normal condition). In the sequence, GPE-EAF and GPE-CHF were evaluated against the oxidative stressor H2O2 in NIH 3T3 cells. A sharp drop in viability was only observed for GPE-CHF, and cytotoxicity of GPE-EAF was considered absent even in a hostile environment. Since GPE-EAF previously developed the best results, its potential performance was investigated in a sunscreen system. The in vitro sun protection factor of the phytoderivative-free formulation was 9.0 + 2.5; by adding GPE-EAF at 10.0%, its efficacy was elevated to 15.0 + 2.5. Both samples suffered a negative effect after artificial ultraviolet exposition (500 W\/m2); however, the presence of GPE-EAF improved the photostability of the sunscreen system.<\/jats:p>","DOI":"10.3390\/cosmetics10010002","type":"journal-article","created":{"date-parts":[[2022,12,21]],"date-time":"2022-12-21T03:31:06Z","timestamp":1671593466000},"page":"2","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Phytocompounds Recovered from the Waste of Cabernet Sauvignon (Vitis vinifera L.)
