INCI: Hypochoeris Radicata Flower Extract

A gentle botanical extract with antioxidant potential, but research is limited and it's not a standout ingredient.

In plain English

Cat's Ear Flower Extract comes from a common wild plant often found in lawns. In skincare, it's used to help calm the skin and fight free radicals (unstable molecules that can damage skin cells). Think of it as a mild, natural helper for sensitive or stressed skin, but it's not a powerhouse ingredient on its own.

What it is

An extract derived from the flowers of Hypochoeris radicata, a perennial herb commonly known as cat's ear or flatweed. It contains flavonoids and other phenolic compounds that contribute to its antioxidant activity.

How it works

The flavonoids in the extract can neutralize free radicals, potentially reducing oxidative stress on the skin. It may also have mild anti-inflammatory effects, helping to soothe irritation and redness.

Pros

Gentle antioxidant

Provides mild protection against free radicals without irritating most skin types, making it suitable for sensitive skin routines.

Soothing potential

May help reduce minor redness or irritation, offering a calming effect in formulations for reactive skin.

Cons and cautions

Limited research

There are very few peer-reviewed studies on this specific extract in topical skincare, so its benefits are not well-established.

Allergen risk

As a member of the Asteraceae plant family, it can trigger allergic reactions in people sensitive to ragweed, marigolds, or daisies.

Best for

  • Those with normal to sensitive skin looking for gentle antioxidant support
  • People interested in natural, plant-based skincare ingredients

Use caution if

  • Individuals with known allergies to ragweed, daisies, or other Asteraceae family plants

Usage tips

Look for products where Cat's Ear Flower Extract is combined with better-studied antioxidants like vitamin C or vitamin E for a more robust effect.
If you have known plant allergies, patch test a product containing this extract before applying it to your face.

Safety summary

Cat's Ear Flower Extract is considered safe for most people when used in cosmetic concentrations. The main risk is allergic contact dermatitis in individuals sensitive to Asteraceae plants. Overall, it has a low irritation and comedogenic profile.
