About
A natural polyphenol antioxidant found in berries and grapes that may help protect skin from oxidative stress.
Piceatannol is a stilbenoid closely related to resveratrol, occurring in foods such as grapes, blueberries, and passion fruit. It demonstrates antioxidant, anti-inflammatory, and tyrosinase-inhibiting properties in vitro. It is not restricted under EU Cosmetics Regulation and is considered safe at cosmetic concentrations, though human clinical data remain limited.
