What it is
An extract derived from the stems of Stephanandra incisa, a deciduous shrub in the rose family. It contains flavonoids and phenolic compounds that give it antioxidant and anti-inflammatory potential.
How it works
The extract's antioxidant compounds neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its anti-inflammatory properties may help reduce redness and calm irritation when applied topically.
Pros
Gentle soothing potential
Early research suggests anti-inflammatory activity, making it a candidate for calming irritated or sensitive skin without harsh effects.
Antioxidant support
Contains flavonoids that may help protect skin from free radical damage caused by UV and pollution, supporting a healthier-looking complexion.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human clinical trials, so its real-world benefits are less certain compared to well-studied botanicals.
Rare ingredient
Not widely used in mainstream products, so it can be harder to find and may be more expensive than common alternatives.
Best for
- People with sensitive or reactive skin looking for a gentle soothing ingredient
- Those seeking antioxidant support from a less common botanical
Use caution if
- Anyone with a known allergy to plants in the Rosaceae family (e.g., roses, strawberries)
