What it is
A natural extract derived from the roots of Nuphar japonica, a water lily native to East Asia. It contains compounds like alkaloids and flavonoids that are thought to have anti-inflammatory and antioxidant effects.
How it works
The extract's flavonoids help neutralize free radicals (unstable molecules that can damage skin cells), while its alkaloids may reduce the production of inflammatory signals in the skin, leading to less redness and irritation.
Pros
Soothing potential
Early research suggests the extract may help calm redness and irritation, making it a good option for sensitive skin types.
Antioxidant support
Flavonoids in the extract can help protect skin from oxidative stress caused by pollution and UV exposure.
Cons and cautions
Limited evidence
Most research is lab-based or early-stage; there are few human studies confirming its effectiveness in skincare.
Rare allergy risk
As with any botanical, 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 a natural antioxidant to complement their routine
