Mangosteen is a purple fruit traditionally grown in Southeast Asia. The fruit (and, particularly, its skin) is rich in antioxidant compounds called xanthones. Xanthones in mangosteen may act as an anti-inflammatory through the inhibitory effects on nitric oxide and prostaglandin E2 release in the body. Mangosteen has been researched for its potential to improve skin elasticity and moisture, potentially through reducing the presence of advanced glycation endproducts, a marker of cellular inflammation.
