What it is
Coreopsis basalis extract is a plant-derived ingredient obtained from the flowers of the plains coreopsis, a member of the aster family. It contains flavonoids and other polyphenolic compounds that can act as antioxidants.
How it works
The extract works primarily by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells. It may also help reduce the production of pro-inflammatory signals in skin cells, leading to a mild soothing effect.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without irritating most skin types, making it suitable for daily use.
Soothing potential
May help reduce visible redness or sensitivity, offering a calming effect for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human trials, so real-world benefits are not firmly proven.
Allergy risk
People with plant allergies, especially to the aster family, could experience contact dermatitis or irritation.
Best for
- Anyone looking for a mild, natural antioxidant in their routine
- Sensitive skin types seeking gentle soothing ingredients
Use caution if
- Individuals with known allergies to coreopsis or aster-family plants (e.g., ragweed, daisies, marigolds)
