When searching for SOD on search engines, you may see various search results. But for skincare enthusiasts, SOD means something exciting: a youthful complexion. SOD is the abbreviation of Superoxide dismutase and the first line of defense against free radical damage, which means it can protect your skin from obvious signs of aging.

What exactly is superoxide dismutase?

Superoxide dismutase is the most powerful antioxidant enzyme in the body. It’s crucial to cellular health because it is the first roadblock that free radicals—unstable atoms that cause premature aging—encounter when they attempt to stir up trouble. If free radicals are the burglars crawling through your window, think of superoxide dismutase as your home alarm system. At the first hint of free radicals, the superoxide dismutase alarm sounds and sends the police, or, in this case, free radical-destroying antioxidants like Vitamin C and Glutathione.

While the police are on their way, superoxide dismutase is hard at work scaring off free radicals by breaking them down into less destructive molecules (hydrogen peroxide and oxygen). This sets the stage for other enzymatic antioxidants to finish the elimination process. And if it weren’t for this alarm, the other antioxidants in your body wouldn’t come to the rescue nearly as fast.In fact, the entire process of eliminating free radicals would be 10,000x slower, leaving a lot more time for cellular damage.

Why do we need to add Superoxide dismutase in our daily skin care?


Most people have already discovered that our skin condition deteriorates day by day after the age of 25.

Actually, this is related to the SOD content in our body. SOD is an antioxidant enzyme that can be synthesized by the human body itself. The age of 25 is the peak period of human SOD content and activity. After the age of 25, as the concentration and activity of the human body’s own synthetic SOD begin to decline, the concentration and activity of SOD in the skin also begin to decline, which is not enough to eliminate the excess free radicals in the body. Excess free radicals will lead to Lipid peroxidation, damage the normal metabolism of the skin, and the skin will look less hydrated.

SOD plays multiple roles in the skin. On the one hand, it inhibits the peroxidation reaction of sebum, effectively fights aging, enhances skin immunity, and protects the skin from external factors such as ultraviolet rays and dust mites.

On the other hand, SOD can also improve cell permeability, promote skin absorption of water, maintain hydration, and keep the skin hydrated and smooth. If combined with hydrolyzed collagen, Hyaluronic acid and other ingredients, SOD can also directly form a protective film against free radicals on the skin surface, and can repair broken skin Elastic fiber.

Because of this effect, adding SOD to cosmetics has become a major trend in high-end skincare products.
