Ingredient review
Cat's Ear Extract
INCI: Hypochoeris Radicata Extract
A gentle botanical extract with antioxidant and soothing potential, but research is limited and it's not a standout ingredient.
In plain English
Cat's Ear Extract comes from a common weed also known as flatweed. In skincare, it's used to help calm irritated skin and fight free radicals (unstable molecules that can damage skin cells). Think of it as a mild, plant-based helper that may support skin comfort and resilience, but it's not a powerhouse ingredient on its own.

What it is
An extract derived from the leaves and roots of Hypochoeris radicata, a perennial herb in the daisy family. It contains flavonoids, phenolic acids, and other antioxidant compounds.
