What it is
An extract derived from the bark of the Lespedeza bicolor plant, a flowering shrub in the pea family. It contains flavonoids and other polyphenolic compounds believed to have antioxidant and anti-inflammatory activity.
How it works
The flavonoids in the extract can neutralize free radicals (unstable molecules that damage skin cells), potentially reducing oxidative stress. Early lab studies also suggest it may calm certain inflammatory pathways, which could help soothe irritated skin.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation sometimes seen with stronger antioxidants like vitamin C, making it suitable for sensitive skin.
Calming potential
Early research suggests it may help reduce redness and inflammation, which can benefit those with reactive or mildly irritated skin.
Cons and cautions
Limited evidence
Most studies are lab-based or early-stage; there aren't enough human trials to confirm how much it actually improves skin appearance or health.
Rarely used alone
It's almost always part of a blend with other extracts, so its individual contribution to a product's effects can be hard to isolate.
Best for
- Anyone looking for a gentle, plant-based antioxidant in their routine
- People with sensitive or easily irritated skin who want a mild soothing ingredient
Use caution if
- Those with known allergies to plants in the Fabaceae (pea) family should patch-test first
Usage tips
Safety summary
Considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible, especially in individuals sensitive to legumes. Always patch-test if you have known plant allergies.
Research notes
Research is in early stages. A few lab studies show antioxidant and anti-inflammatory activity, but there are no robust clinical trials on human skin. More evidence is needed to confirm its efficacy.
Common label clues
