Superoxide dismutase (SOD) is an enzymatic antioxidant that catalyzes the conversion of superoxide radicals into oxygen and hydrogen peroxide, helping protect skin cells from oxidative stress and free-radical damage. In topical formulations it is used to support antioxidant defenses and may aid in reducing signs of environmental aging.
