Ingredient review
Uapaca Bojeri Leaf Extract
INCI: Uapaca Bojeri Leaf Extract
A gentle, antioxidant-rich leaf extract that may help calm and protect skin, though research is still emerging.
In plain English
This is an extract made from the leaves of the Uapaca bojeri tree, also known as the tapia tree, which grows in Madagascar. In skincare, it is used for its antioxidant content, meaning it can help neutralize free radicals that damage skin cells. It also has mild soothing properties, making it a nice addition to products aimed at sensitive or stressed skin. Because it is not as widely studied as some other botanicals, its benefits are based on traditional use and early research rather than large clinical trials.

What it is
A natural plant extract derived from the leaves of the Uapaca bojeri tree, a species native to Madagascar. The extract is rich in polyphenols and flavonoids, which are compounds known for their antioxidant and anti-inflammatory activity.
How it works
When applied to the skin, the polyphenols in the extract help scavenge free radicals—unstable molecules that can cause oxidative stress and premature aging. This can help protect skin cells from environmental damage. Additionally, the flavonoids may reduce the production of inflammatory signals, leading to a mild calming effect on irritated skin.
Pros
Gentle antioxidant support
Provides a mild shield against free radicals without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin types.
Soothing potential
Early research and traditional use suggest it can help calm redness and discomfort, which is helpful for reactive or stressed skin.
Cons and cautions
Limited research
Most evidence comes from traditional use and lab studies, not large clinical trials on humans, so the full range of benefits and risks is not well established.
Rare allergy risk
As with any botanical, there is a small chance of allergic contact dermatitis, especially for those with plant allergies.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- People with sensitive or easily irritated skin who want soothing ingredients
Use caution if
- Individuals with known allergies to plants in the Phyllanthaceae family should patch test first
