What it is
Pterocarpus marsupium leaf extract is a natural ingredient derived from the leaves of the Indian kino tree, a tree native to India and Southeast Asia. The extract contains flavonoids and other polyphenolic compounds that are believed to have antioxidant and anti-inflammatory properties.
How it works
In a cosmetic product, this extract works primarily by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also help reduce the production of pro-inflammatory signals in the skin, leading to a calming effect. However, the exact mechanisms are not fully established in peer-reviewed cosmetic science.
Pros
Gentle antioxidant
Helps protect skin from free radical damage without causing irritation, making it suitable for daily use in serums and moisturizers.
Low irritation risk
Unlikely to clog pores or cause stinging, so it can be a good option for sensitive or acne-prone skin types.
Cons and cautions
Limited research
Most evidence comes from traditional use or lab studies; there are few rigorous human trials confirming its topical benefits for skin.
Potential allergen
As a plant extract, it may cause contact dermatitis in very rare cases, especially in those with legume allergies.
Best for
- Anyone looking for a gentle antioxidant boost in their routine
- Those with normal to combination skin who want a plant-based soothing ingredient
Use caution if
- Individuals with known allergies to legumes or plants in the Fabaceae family should patch-test first
