Ingredient review
Pisonia Grandis Leaf Extract
INCI: PISONIA GRANDIS LEAF EXTRACT
A gentle botanical extract with antioxidant potential, but research on its specific skincare benefits is still limited.
In plain English
Pisonia grandis leaf extract comes from the leaves of a tropical tree sometimes called the lettuce tree. In skincare, it's used mainly for its antioxidant content, which can help protect skin from environmental stressors. Because it's a newer ingredient in cosmetics, there isn't a lot of published research yet, but early indications suggest it may also have mild soothing properties. It's generally considered safe and non-irritating for most skin types.

What it is
Pisonia grandis leaf extract is a natural plant extract obtained from the leaves of the Pisonia grandis tree, a species native to coral atolls and coastal regions of the Indian and Pacific Oceans. The leaves are rich in flavonoids and other polyphenolic compounds that act as antioxidants.
How it works
In a cosmetic product, the extract delivers antioxidant compounds to the skin's surface. These compounds help neutralize free radicals—unstable molecules from UV exposure and pollution that can damage skin cells and accelerate visible aging. The extract may also provide mild anti-inflammatory effects, helping to calm redness or irritation.
Pros
Gentle antioxidant
Provides antioxidant benefits without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Soothing potential
Early research suggests anti-inflammatory activity, which may help calm redness and irritation in daily skincare routines.
Cons and cautions
Limited research
There are very few peer-reviewed studies specifically on Pisonia grandis leaf extract in cosmetic applications, so its benefits are not as well-established as more common botanicals.
Sustainability questions
Pisonia grandis grows in specific island ecosystems; overharvesting could impact local biodiversity. Look for brands that source responsibly.
Best for
- Anyone looking for a gentle, natural antioxidant ingredient
- People with sensitive or reactive skin who want extra protection without irritation
Use caution if
- Those with known allergies to plants in the Nyctaginaceae family (rare)
