Ingredient review
Catalpa Bark & Leaf Extract
INCI: Catalpa Ovata Bark/Leaf Extract
A gentle botanical extract with antioxidant potential, but research on its cosmetic benefits is still limited.
In plain English
Catalpa bark and leaf extract comes from a tree native to East Asia. In skincare, it's used mainly for its antioxidant properties, meaning it can help protect your skin from damage caused by environmental stressors like pollution and UV rays. It also has some soothing qualities, which may calm irritated skin. However, most of the evidence comes from lab studies, not large human trials, so its effects are not as well-documented as more common ingredients like green tea or vitamin C.

What it is
An extract derived from the bark and leaves of the Catalpa ovata tree, a species in the trumpet vine family. It contains various plant compounds such as flavonoids, phenolic acids, and iridoids, which are thought to contribute to its antioxidant and anti-inflammatory activity.
How it works
The extract works by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. Its phenolic compounds may also inhibit certain enzymes involved in inflammation, helping to reduce redness and irritation when applied topically.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may calm redness and inflammation, offering a mild anti-irritant benefit.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human trials confirming its effectiveness in real-world skincare use.
Less common ingredient
Not widely studied or used in mainstream products, so long-term safety data is sparse compared to well-established botanicals.
Best for
- Anyone looking for a gentle antioxidant ingredient
- Those with normal to combination skin seeking light protection
Use caution if
- Individuals with known allergies to Catalpa or related plants (Bignoniaceae family)
Usage tips
