What it is
An extract derived from the flowers, leaves, and stems of Ageratum conyzoides, a plant in the daisy family. It contains various compounds like flavonoids and coumarins that are thought to have antioxidant and anti-inflammatory activity.
How it works
The flavonoids in the extract can neutralize free radicals, potentially reducing oxidative stress on the skin. Some compounds may also calm minor irritation by modulating inflammatory pathways, though the exact mechanism in topical use is not fully established.
Pros
Gentle antioxidant
Contains flavonoids that can help protect skin from free radical damage without causing irritation for most users.
Soothing potential

Cons and cautions
Limited research
Most studies are on the plant's general properties, not specifically on cosmetic use in humans. Efficacy in skincare is not well-documented.
Allergy risk
As a member of the Asteraceae family, it may cause allergic reactions in people sensitive to ragweed, marigolds, or daisies.
