Ingredient review
Pterocarpus Marsupium Extract
INCI: PTEROCARPUS MARSUPIUM BARK/WOOD EXTRACT
A gentle plant extract with antioxidant potential, but research in topical skincare is still limited.
In plain English
Pterocarpus marsupium extract comes from the bark and wood of a tree native to India, often called Indian Kino. In skincare, it's used mainly for its antioxidant properties, meaning it can help protect your skin from damage caused by environmental stressors like pollution and UV rays. It also has some soothing qualities, which may calm irritated skin. However, most of the research on this ingredient has been done on its internal use (like for blood sugar control), so its benefits when applied to the skin are less proven.
