INCI: Ilex Aquifolium Leaf Extract
A gentle plant extract that may help protect skin from environmental stress, though research is still early.
In plain English
Holly leaf extract comes from the leaves of the English holly plant. In skincare, it's used mainly for its antioxidant content, which can help defend skin against damage from pollution and UV exposure. It also has mild soothing properties, making it a nice addition for sensitive or irritated skin. However, it's not a powerhouse ingredient and is best used as part of a broader antioxidant blend.
