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 Poa annua, a widespread annual grass species. The extract contains various plant compounds, including flavonoids and phenolic acids, which are believed to have antioxidant and anti-inflammatory properties.
How it works
The extract is thought to work by providing antioxidant compounds that can neutralize free radicals, potentially reducing oxidative stress on the skin. It may also help calm minor irritation by influencing inflammatory pathways, though the exact mechanisms are not fully understood.
Pros
Gentle and low-risk
The extract has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Antioxidant potential
Lab studies suggest the extract contains compounds that can fight free radicals, which may help protect skin from premature aging caused by pollution and UV exposure.
Cons and cautions
Limited human evidence
Most research on Poa annua extract is in test tubes or animals. There are no robust clinical studies showing clear benefits for human skin.
Uncertain efficacy
Because the evidence is still emerging, it's unclear how much of the antioxidant activity actually translates to visible skin improvements in real-world use.
Best for
- People with normal to combination skin looking for gentle antioxidant support
- Those interested in trying novel plant-based ingredients
Use caution if
- Individuals with known grass allergies should patch test first
- Anyone seeking proven, high-efficacy ingredients may prefer more researched options
Usage tips
Safety summary
