[Christman L (2024); evidence level 2] - This study aimed to determine whether a polyphenol-rich cranberry beverage affects skin properties, lipids, and the microbiome in women using a randomized, double-blinded, placebo-controlled, cross-over design. [Christman L (2024); evidence level 2] - Hydroxytyrosol (HT), mainly found in olive fruit and oil, is known for its powerful antioxidant and anti-inflammatory properties including inhibition of prostaglandin E2 (PGE) and nitric oxide (NO) production pathways.
