Superoxide Dismutase
What is Superoxide Dismutase?
Superoxide Dismutase, often abbreviated as SOD, is a vital enzyme present in nearly all living organisms, including humans, plants, and microorganisms. It functions by rapidly converting superoxide anion radicals—one of the most damaging reactive oxygen species—into oxygen and hydrogen peroxide, which are then further neutralized by other cellular defenses. In cosmetics, it appears in forms derived from sources like yeast, bovine erythrocytes, or recombinant technology, typically stabilized in liposomes for better skin penetration. Commonly found in anti-aging serums, creams, and sunscreens, it serves primarily as an antioxidant to shield formulations from oxidation and as a skin conditioning agent to enhance moisture retention and suppleness. Its role supports product stability while contributing to skin's resilience against environmental oxidative stressors.
