What it is
A natural extract derived from the flowers of Heterotheca inuloides, also known as Mexican arnica. It contains compounds like flavonoids and sesquiterpenes that give it antioxidant and anti-inflammatory properties.
How it works
The flavonoids in the extract neutralize free radicals, which are unstable molecules that can damage skin cells. Its anti-inflammatory compounds may help calm irritated skin by reducing the production of pro-inflammatory signals.
Pros
Gentle soothing
May help calm redness and irritation without harsh side effects, making it suitable for sensitive skin routines.
Antioxidant support
Provides a natural source of antioxidants that can help protect skin from daily environmental damage like pollution and UV exposure.
Cons and cautions
Limited research
Most evidence comes from traditional use and lab studies; there are few robust human trials confirming its skincare benefits.
Allergy risk
As a member of the Asteraceae family, it may cause allergic reactions in people sensitive to ragweed, marigolds, or daisies.
Best for
- People with sensitive or easily irritated skin
