In plain English

Holly leaf extract comes from the leaves of the English holly plant.

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.

What it is

A water- or alcohol-based extract of Ilex aquifolium leaves, rich in polyphenols and flavonoids that act as antioxidants.

How it works

  • People with sensitive skin who want extra protection without irritation

Use caution if
