What it is
Siberian iris root extract is a natural botanical ingredient derived from the roots of Iris sibirica, a flowering plant native to Europe and Asia. It contains various compounds like flavonoids and polysaccharides that are thought to have soothing and antioxidant effects.
How it works
In a cosmetic product, Siberian iris root extract is believed to work by providing antioxidant compounds that help neutralize free radicals—unstable molecules that can damage skin cells. It may also have mild anti-inflammatory properties that help calm redness and irritation, though the exact mechanisms are not fully understood.
Pros
