In the latest study published in the American Journal of Dermatology, researchers at the University of Alabama at Birmingham found that grapes contain a variety of grape polyphenols, mainly flavanol catechins, epicatechin and proanthocyanidins, resveratrol and ellagic acid, and many of these compounds carry antioxidant, anti-inflammatory and anti-tumor effects.
In the team’s 14-day experiment, a total of 19 volunteers in good health participated, taking 75 grams of freeze-dried grape powder day by day, and the results showed that the degree of natural protection of the skin of these people increased by 74.8 %.
