What it is
A natural extract derived from the flowers of Populus tremuloides, a tree native to North America. The extract contains flavonoids and phenolic compounds that give it antioxidant and anti-inflammatory potential.
How it works
The flavonoids in aspen flower extract help neutralize free radicals, which are unstable molecules that can damage skin cells. Its phenolic compounds may also reduce the activity of enzymes that cause inflammation, leading to a soothing effect on irritated skin.
Pros

May help reduce redness and irritation without harsh side effects, making it suitable for sensitive skin.
Antioxidant support
Provides a mild shield against free radicals from pollution and UV exposure, supporting overall skin health.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world effectiveness is not fully proven.
Potential allergen
Contains salicylates, which can trigger reactions in people with aspirin sensitivity or birch pollen allergies.
Best for

- Those looking for a gentle antioxidant in their routine
Use caution if
