Gamma-mangosteen (a compound from mangosteen fruit) protected skin cells from UV damage better than other mangosteen types, boosting the skin's natural antioxidant defenses and reducing collagen-breaking enzymes by 29%. In mice exposed to UVB rays, it reduced signs of skin aging and helped maintain skin elasticity and firmness.

Researchers tested gamma-mangosteen in human skin cells and on mice using multiple antioxidant assays and UV exposure protocols. They measured specific proteins and enzymes involved in aging to understand how the compound works.
