Ingredient review
Macropiper Excelsum Leaf Powder
INCI: MACROPIPER EXCELSUM LEAF POWDER
A gentle botanical powder with traditional soothing and antioxidant potential, but scientific research on its cosmetic benefits is still limited.
In plain English
Macropiper excelsum leaf powder is made from the dried and ground leaves of a shrub native to New Zealand, sometimes called kawakawa. In skincare, it is used as a mild exfoliant or as a source of antioxidants that may help calm the skin. Because it is a natural plant material, its exact composition can vary, and there is not yet a large body of scientific studies confirming its effectiveness in cosmetics.
