SOD (Superoxide dismutase)

SOD, an antioxidant enzyme for skin care

SOD, short for Superoxide Dismutase, is an enzyme powder with the INCI Superoxide Dismutase. In cosmetics it is valued as an antioxidant ingredient that supports a product's defense story against free radicals caused by daily sun exposure and pollution. You can buy it from a 10 g pack, which goes a long way because the enzyme is used at small doses, up to bulk packs for production.

Products that feature SOD

The enzyme is a natural fit for appearance-focused cosmetic serums and creams, day creams with an anti-pollution claim, eye care and after-sun lotions. Brands use it to give a formula a more complete antioxidant profile next to vitamins and plant extracts. Low levels, often well under 1%, are typical, and the supplier dose on the lot documents should be the guide.

Antioxidant partners

SOD is often combined with other antioxidants that act in different phases. Ferulic acid works well in water-based serums, and ectoin adds a skin-comfort story for products used after sun exposure. Compare more options in our cosmetic actives section.

Keeping the enzyme active

Enzymes are sensitive to heat and extreme pH. Add SOD to the water phase at the end of production, below about 40 °C, and keep the finished pH close to skin range. Store the powder tightly closed in a cool, dry place, ideally refrigerated once opened. For wholesale volumes above 1 kg, request a bulk quote from the supplier specification. It ships from Florida, usually within 1 to 2 business days, in the pack sizes shown above, and US shipping is free on orders of $50 or more.
