What it is
A botanical extract obtained from the aerial parts (flower, leaf, stem) of Crepis sibirica, a plant native to Siberia and parts of Asia. It is rich in flavonoids and phenolic compounds, which are known for their antioxidant activity.
How it works
The extract works primarily by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. This antioxidant action helps reduce oxidative stress on the skin. Additionally, some compounds in the extract may help calm inflammation by inhibiting certain pro-inflammatory pathways, leading to a soothing effect.
Pros
Gentle antioxidant support
Provides a mild, natural way to help protect skin from daily environmental stressors without causing irritation, making it suitable for sensitive skin types.
Soothing potential
May help reduce redness and calm skin after exposure to irritants, offering a comforting effect for those with easily upset skin.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; there are few clinical trials on humans to confirm specific benefits for skin aging or conditions.
Allergy risk for some
As a member of the Asteraceae plant family, it could trigger allergic reactions in people sensitive to related plants like chamomile or marigold.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- People with sensitive or reactive skin who want soothing ingredients
Use caution if
- Individuals with known allergies to plants in the Asteraceae family (e.g., daisies, ragweed) should patch test first
