Ingredient review
Pourthiaea Leaf Extract
INCI: Pourthiaea Villosa Leaf Extract
A gentle plant extract with antioxidant potential, but research is limited and benefits are not yet well-established.
In plain English
Pourthiaea leaf extract comes from a shrub native to East Asia. In skincare, it's added to help protect skin from environmental stress and calm minor irritation. Because it's a natural extract, its exact composition can vary, and there isn't a lot of human research yet to confirm how well it works compared to more studied antioxidants like vitamin C.

What it is
An extract made from the leaves of Pourthiaea villosa, a plant in the rose family. It contains natural compounds like flavonoids and phenolic acids that may have antioxidant activity.
