The current Migaku evidence database contains 2 reusable source documents for Cranberry Skin Health Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - Six weeks of cranberry beverage significantly reduced UVB-induced erythema, improved net elasticity on the face and forearm, smoothness on the face, and gross elasticity on the forearm compared to the placebo. [Christman L (2024); evidence level 2] - SOD activities were improved after six weeks of cranberry beverage consumption compared to the placebo, while glutathione peroxide and TNF-α were improved compared to baseline. [Christman L (2024); evidence level 2] - Consumption of a cranberry beverage for six weeks improved specific skin properties and oxidative stress and modulated skin lipids and microbiome compared to placebo. [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. [Guillemet Damien (2025); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
