Ingredient review
Japanese Ardisia Extract
INCI: Ardisia Japonica Branch/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
Japanese ardisia extract comes from a shrub native to East Asia. In skincare, it's added for its antioxidant content, which may help protect skin from environmental stress. However, most of what we know comes from lab studies, not human trials, so it's best seen as a supportive ingredient rather than a star performer.
