Annual Fleabane Leaf Extract
INCI: Erigeron Annuus Leaf Extract
A gentle plant extract with antioxidant potential, but research on its skincare benefits is still limited.
In plain English
Annual fleabane leaf extract comes from a common wildflower. In skincare, it's used mainly for its antioxidant content, which may help protect skin from environmental stress. It's considered very gentle and unlikely to cause irritation, but there isn't a lot of human research yet to confirm strong anti-aging or brightening effects.

What it is
A natural extract derived from the leaves of Erigeron annuus, a flowering plant in the aster family. It contains flavonoids and other polyphenolic compounds that act as antioxidants.
How it works
The flavonoids in the extract help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It may also have mild anti-inflammatory effects, helping to calm redness or sensitivity.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
May help calm minor redness or sensitivity, adding a comforting effect to daily skincare.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human trials, so real-world anti-aging benefits are not well proven.
Variable potency
The concentration of active compounds can differ between batches, leading to inconsistent results in products.
Best for
- Anyone looking for a gentle antioxidant ingredient
- Those with sensitive or reactive skin who want extra soothing support
Use caution if
- People with known allergies to aster family plants (e.g., ragweed, daisies)
