What it is
A water- or solvent-based extract derived from the whole plant of Taraxacum hallaisanensis, a rare dandelion species endemic to the highlands of Jeju Island, South Korea. It contains flavonoids, phenolic acids, and other bioactive compounds.
How it works
The extract's antioxidant compounds neutralize free radicals (unstable molecules that can damage skin cells), helping to prevent oxidative stress. Its anti-inflammatory properties may reduce redness and soothe sensitivity by calming the skin's immune response.
Pros
Gentle antioxidant
Provides antioxidant benefits without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Soothing potential
Early research suggests it may help calm redness and inflammation, which is helpful for reactive or stressed skin.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; there are few human clinical trials confirming its benefits in skincare products.
Rare allergen risk
People with allergies to dandelion or related plants (Asteraceae family) may experience a reaction, though this is uncommon.
Best for
- Anyone looking for a gentle, natural antioxidant
- People with sensitive or easily irritated skin who want extra protection
Use caution if
- Individuals with known allergies to dandelion or plants in the Asteraceae family (e.g., ragweed, marigolds, daisies)
