Ingredient review
Perennial Ryegrass Flower Extract
INCI: LOLIUM PERENNE FLOWER EXTRACT
A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
This is an extract made from the flowers of perennial ryegrass, a common grass species. In skincare, it's added to products for its antioxidant content, which may help protect skin from environmental stressors like pollution. However, there isn't much research yet on how well it works on human skin, so its benefits are mostly theoretical based on lab studies.

What it is
A botanical extract derived from the flowers of Lolium perenne, also known as perennial ryegrass. It contains various plant compounds like flavonoids and phenolic acids that have antioxidant activity in laboratory tests.
How it works
In a cosmetic product, it is thought to work by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells. This antioxidant action may help reduce oxidative stress on the skin, potentially slowing signs of aging caused by environmental factors.
Pros
Gentle on skin
Unlikely to cause irritation or clog pores, making it suitable for sensitive skin types when used at typical concentrations.
Natural origin
Derived from a renewable plant source, appealing to consumers seeking naturally-sourced skincare ingredients.
Cons and cautions
Limited evidence
Most research is in test tubes or on animals, not on human skin, so real-world benefits are uncertain.
Potential allergen
As a grass extract, it may trigger allergic reactions in people with grass pollen allergies, though this is rare in topical use.
Best for
- People looking for gentle, plant-based antioxidant ingredients
- Those with normal to dry skin who want extra environmental protection
Use caution if
- Individuals with known allergies to grass pollen should patch test first
Usage tips
Safety summary
Considered safe for topical use at typical cosmetic concentrations. The main concern is potential allergy in grass-sensitive individuals, which is rare. No known toxicity or irritation in standard safety assessments.
Research notes
Research is preliminary. Laboratory studies show antioxidant activity, but there are no published clinical trials on human skin confirming anti-aging or protective benefits. More studies are needed.
