Ingredient review
Bush Clover Extract
INCI: Lespedeza Cyrtobotrya Extract
A gentle botanical extract with antioxidant potential, but research is limited and benefits are not yet well-established in human skin.
In plain English
Bush clover extract comes from a plant in the legume family. In skincare, it's added for its ability to fight free radicals (unstable molecules that can damage skin) and calm irritation. Think of it as a mild, plant-based helper that may support your skin's defenses, but it's not a powerhouse ingredient on its own.

What it is
An extract derived from the leaves or stems of Lespedeza cyrtobotrya, a shrub native to East Asia. It contains flavonoids and other polyphenolic compounds that give it antioxidant activity.
How it works
The flavonoids in bush clover extract help neutralize free radicals, which are caused by UV exposure and pollution. This can reduce oxidative stress on skin cells. Some compounds in the extract may also have mild anti-inflammatory effects, helping to calm redness or irritation.
Pros
Gentle antioxidant
Provides a mild defense against free radicals without common irritation, making it suitable for sensitive skin types.
Soothing potential
May help calm minor redness or inflammation, offering a dual benefit of protection and comfort.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human trials, so its real-world effectiveness on skin is not well-proven.
Low potency
As a single botanical extract, it is less potent than concentrated antioxidants like vitamin C or ferulic acid, so it works best in a blend.
Best for
- Anyone looking for a gentle, plant-based antioxidant in their routine
- Those with normal to combination skin who want extra environmental protection
Use caution if
- Individuals with known allergies to legumes or plants in the Fabaceae family
