Ingredient review
Walter's Dogwood Leaf Extract
INCI: CORNUS WALTERI LEAF EXTRACT
A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
This is an extract made from the leaves of Walter's dogwood, a tree native to East Asia. In skincare, it's added for its ability to help protect skin from environmental stress and calm minor irritation. Because it's a natural plant extract, its exact composition can vary, and most of what we know comes from lab studies rather than human trials.
