Kummerowia Striata Root Extract
INCI: KUMMEROWIA STRIATA ROOT EXTRACT
A gentle botanical root extract with traditional use for soothing skin, but modern cosmetic evidence is still limited.
In plain English
Kummerowia striata root extract comes from a plant in the legume family, sometimes called Chinese lespedeza. In skincare, it's used mainly for its potential to calm irritation and provide antioxidant protection. Think of it as a mild, plant-based helper that may support skin comfort and defend against environmental stress, though it hasn't been studied as extensively as more common ingredients like green tea or chamomile.

What it is
Kummerowia striata root extract is a natural ingredient derived from the roots of the Kummerowia striata plant, a flowering herb native to East Asia. The extract is typically obtained through solvent or water-based extraction and contains various phytochemicals, including flavonoids and phenolic compounds, which are believed to contribute to its soothing and antioxidant effects.
How it works
In a cosmetic product, this extract is thought to work by delivering antioxidant compounds that can help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. Its soothing properties may come from flavonoids that help calm inflammatory responses in the skin, potentially reducing redness and sensitivity. However, the exact mechanisms are not fully characterized in peer-reviewed cosmetic science literature.
Pros
Gentle soothing potential
Traditional use and early research suggest it may help calm skin irritation without the harshness of some synthetic actives, making it suitable for sensitive skin routines.
Antioxidant support
Contains flavonoids that can help protect skin from oxidative stress caused by pollution and UV exposure, supporting overall skin health over time.
Cons and cautions
Limited modern evidence
There are very few peer-reviewed studies specifically on Kummerowia striata root extract for topical cosmetic use, so its benefits are largely based on traditional knowledge and preliminary data.
Rare but possible allergen
As a legume-derived ingredient, it may cause allergic reactions in individuals with legume allergies, though such cases are not well-documented in cosmetics.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Those interested in trying traditional botanical extracts with antioxidant potential
Use caution if
- Individuals with known allergies to legumes (Fabaceae family) should patch-test first
Usage tips
Safety summary
Kummerowia striata root extract is considered safe for topical cosmetic use at typical concentrations. Irritation and allergy risks are low, but as with any botanical, patch-testing is recommended for those with sensitive skin or legume allergies. There are no known significant safety concerns from available data.
Research notes
Research on Kummerowia striata root extract in cosmetics is very limited. Most information comes from traditional use and a small number of in vitro studies suggesting antioxidant and anti-inflammatory activity. High-quality clinical trials on human skin are lacking, so the evidence level is considered emerging.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for use in cosmetics when used at typical concentrations, though specific regulations vary by country. In the EU and US, it is not restricted but must be used in accordance with good manufacturing practices.
