What it is
An extract made from the leaves of Eschscholzia californica, a flowering plant native to the western United States. The extract contains alkaloids and flavonoids believed to have calming and antioxidant effects.
How it works
The extract's flavonoids help neutralize free radicals (unstable molecules that can damage skin cells), while its alkaloids may interact with skin receptors to reduce the sensation of irritation or redness. It works gently, without harsh chemicals.
Pros
Gentle soothing
May help reduce visible redness and discomfort without causing stinging or irritation, making it a good choice for reactive skin.
Antioxidant support
Contains flavonoids that can help protect skin from daily environmental damage like pollution and UV exposure.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use, not large human trials, so its exact benefits in skincare are not fully proven.

As a botanical extract, it can cause allergic reactions in rare cases, especially in those with plant allergies.
Best for
