Ingredient review
Paulownia Leaf Extract
INCI: Paulownia Tomentosa Leaf Extract
A gentle, antioxidant-rich plant extract that may help calm skin and protect against environmental stress, though research is still early.
In plain English
Paulownia leaf extract comes from the leaves of the fast-growing Paulownia tree (also called the empress tree). In skincare, it's used for its antioxidant content, which can help neutralize free radicals from pollution and UV exposure. It also has mild soothing properties, making it a nice addition for sensitive or irritated skin. Because it's relatively new in cosmetics, most evidence is preliminary, but it's generally considered safe and non-irritating.

What it is
A water-soluble extract derived from the leaves of Paulownia tomentosa, a tree native to East Asia. It contains flavonoids, phenolic acids, and other plant compounds with antioxidant and anti-inflammatory activity.
How it works
The flavonoids in paulownia leaf extract help scavenge free radicals, reducing oxidative stress on the skin. Some compounds also inhibit pro-inflammatory enzymes, which can help calm redness and irritation. It does not exfoliate or alter the skin barrier directly.
Pros
Gentle antioxidant
Provides free-radical protection without irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it can help calm redness and inflammation, which is useful for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human trials confirming its benefits in skincare.

As with any botanical, there is a small chance of contact allergy, especially for those with plant sensitivities.
Best for
- Anyone looking for extra antioxidant protection in their routine
- People with sensitive or easily irritated skin who want a gentle soothing ingredient
Use caution if
- Individuals with a known allergy to Paulownia or related plants (Bignoniaceae family)
