Summary: Cerium oxide nanoparticles (nanoceria) are biocompatible and multifunctional nanozymes that mimic the activities of superoxide-dismutase and catalase. They can shield from UV exposure, protect tissues from oxidative damage, and accelerate the recovery of skin cells. Nanoceria can also neutralize the side effects of titanium dioxide nanoparticles, a common ingredient in UV-shielding lotions. These properties make nanoceria a promising solution for preventing UV-induced skin damage and carcinogenesis.
