Ingredient review
Melicope Hayesii Leaf Extract
INCI: Melicope Hayesii Leaf Extract
A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
Melicope hayesii leaf extract comes from a tree native to parts of Australia and the Pacific. In skincare, it's added to help protect skin from environmental stress thanks to natural compounds called flavonoids. Think of it like a mild shield for your skin, but it's not a powerhouse ingredient on its own.

What it is
A natural extract derived from the leaves of the Melicope hayesii tree, containing flavonoids and other plant compounds with antioxidant activity.
How it works
The flavonoids in the extract can neutralize free radicals—unstable molecules that damage skin cells and accelerate aging. This helps reduce oxidative stress on the skin, potentially supporting a calmer, more even complexion over time.
Pros
Gentle antioxidant
Provides a mild layer of protection against free radicals without irritating most skin types.
Soothing potential
Early research suggests it may help calm redness or sensitivity, making it suitable for reactive skin.
Cons and cautions
Limited evidence
Most benefits are based on lab studies, not large human trials, so real-world effects are less certain.
Rare allergen risk
As a plant extract, it can cause allergic reactions in people sensitive to related botanical families.
Best for
- Anyone looking for a mild antioxidant boost in their routine
- Sensitive skin types seeking gentle plant-based ingredients
Use caution if
- Those with known allergies to plants in the Rutaceae family (citrus family)
