Ingredient review
Engelhardtia Leaf Extract
INCI: Engelhardtia chrysolepis leaf extract
A gentle plant extract with antioxidant potential, but research is limited and benefits are not yet well-established.
In plain English
Engelhardtia leaf extract comes from a tree native to parts of Asia. In skincare, it's used as an antioxidant to help protect skin from environmental stress, and it may have mild soothing properties. Because it's not widely studied, its effects are less certain compared to more common antioxidants like vitamin C or green tea.

What it is
An extract made from the leaves of Engelhardtia chrysolepis, a tree in the walnut family. It contains natural compounds like flavonoids and tannins that can act as antioxidants.
How it works
The flavonoids in the extract help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. This may reduce oxidative stress on the skin. The tannins may also provide mild astringent and soothing effects.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Natural origin
Derived from a plant source, appealing to consumers who prefer naturally sourced ingredients.
Cons and cautions
Limited evidence
Few peer-reviewed studies confirm its effectiveness on human skin, so benefits are less certain than with well-researched antioxidants.
Rare allergen risk
As a plant extract, it may cause allergic reactions in individuals sensitive to tree nuts or related species.
Best for
- Anyone looking for a gentle, plant-based antioxidant
- Those with normal to combination skin seeking extra protection
Use caution if
- People with known allergies to walnut family plants
- Those seeking proven, high-efficacy antioxidants
