What it is
A natural extract obtained from the dried root of Saururus chinensis, a perennial herb native to East Asia. It contains compounds like flavonoids and lignans that are thought to have anti-inflammatory and antioxidant activity.
How it works
The extract's flavonoids and other polyphenols can neutralize free radicals (unstable molecules that damage skin cells). It may also reduce the production of pro-inflammatory signals in skin cells, helping to calm redness and irritation when applied topically.
Pros
Soothing potential
Early research suggests it can help calm skin irritation and redness, making it a good option for sensitive skin routines.
Antioxidant support
Contains flavonoids that may help protect skin from oxidative stress caused by UV and pollution, supporting overall skin health.
Cons and cautions
Limited human evidence
Most studies are lab-based or on animals; there aren't many human trials confirming its effectiveness in skincare products.
Rare allergy risk
As with any plant extract, there is a small chance of allergic reaction, especially for those with plant allergies.
Best for
- People with sensitive or easily irritated skin
- Those looking for additional antioxidant support in their routine
