What it is
An extract derived from the leaves (needles) of the Japanese yew tree, a conifer native to East Asia. It contains compounds like flavonoids, phenolic acids, and taxanes, which are known for antioxidant and anti-inflammatory activity.
How it works
The extract delivers antioxidants to the skin surface, which can neutralize free radicals (unstable molecules that cause premature aging). It may also reduce the activity of inflammatory messengers in skin cells, helping to calm irritation and support a more even skin tone.
Pros
Antioxidant support
Helps protect skin from daily environmental damage like pollution and UV exposure, which can lead to premature aging.
Soothing potential
May calm minor redness or irritation, making it a good addition for sensitive skin types when used at low concentrations.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; there aren't many human trials confirming its effectiveness in skincare.
Allergy risk
As a botanical extract, it can cause allergic reactions in rare cases, especially if you are sensitive to conifer plants.
Best for
- Anyone looking for extra antioxidant protection in their routine
- People with normal to combination skin who want a gentle, plant-based ingredient
Use caution if
- Individuals with known allergies to yew or conifer plants should patch test first
