What it is
An extract obtained from the seeds of Penthorum chinense, a perennial herb native to East Asia. The extract contains flavonoids and polyphenols that give it antioxidant and anti-inflammatory properties.
How it works
The flavonoids in the extract help neutralize free radicals (unstable molecules that can damage skin cells), while other compounds may reduce the production of inflammatory signals in the skin. This dual action helps protect skin from environmental stressors and supports a calmer complexion.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm redness and inflammation, supporting a more even skin tone.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; human skincare trials are scarce, so effectiveness is not fully proven.
Rare allergen risk
As with any botanical, there is a small chance of allergic reaction, especially for those with plant allergies.
Best for
- Anyone looking for a gentle, plant-based antioxidant
- People with normal to sensitive skin seeking soothing ingredients
