Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

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

Usage tips

Look for this extract in serums or moisturizers where it can be paired with other antioxidants like vitamin C for enhanced protection.
Store products containing this extract away from direct sunlight and heat to preserve its antioxidant potency.

Safety summary

Considered safe for topical use in cosmetics at typical concentrations. Patch testing is recommended for individuals with plant allergies, especially to the Asteraceae family. No significant toxicity or irritation has been reported in available data.

Research notes

Research on Crepis sibirica extract is limited. In vitro studies suggest antioxidant and anti-inflammatory activities due to its flavonoid content. Human clinical data is lacking, so benefits are inferred from traditional use and related species.
