Ingredient review
Foxtail Grass Extract
INCI: Vulpia myuros extract
A gentle botanical extract with antioxidant potential, but research on its skincare benefits is still limited.
In plain English
Foxtail grass extract comes from a type of wild grass. In skincare, it's used mainly as an antioxidant to help protect skin from environmental stress, and it may have mild soothing effects. Because it's not widely studied, its benefits are less proven compared to more common plant extracts like green tea or chamomile.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
An extract derived from the aerial parts of Vulpia myuros, a grass species commonly known as foxtail or rat's-tail fescue. It contains various phytochemicals, including flavonoids and phenolic compounds, which contribute to its antioxidant activity.
How it works
The extract's antioxidant compounds help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its soothing properties may come from anti-inflammatory compounds that calm irritated skin, though the exact mechanisms are not fully characterized.
Pros
Natural antioxidant
Contains flavonoids that help protect skin from free radical damage caused by UV and pollution.
Low irritation potential
Generally well-tolerated, making it suitable for sensitive skin types when used at typical concentrations.
Cons and cautions
Limited research
There are very few peer-reviewed studies on Vulpia myuros extract in skincare, so its benefits are not as well-established as other botanicals.
Potential allergen
As a grass-derived ingredient, it may cause allergic reactions in people with grass pollen allergies, though this is rare in topical use.
Best for
- Those looking for a gentle, natural antioxidant ingredient
- People with normal to oily skin seeking lightweight protection
Use caution if
- Individuals with known allergies to grasses or related plants
- Those seeking proven, high-efficacy antioxidants should opt for better-studied options
