Ingredient review
Cyperus Rotundus Fruit Extract
INCI: CYPERUS ROTUNDUS FRUIT EXTRACT
A plant-based extract with antioxidant potential, but research in cosmetics is still limited.
In plain English
Cyperus Rotundus Fruit Extract comes from the fruit of a plant often called nutgrass or purple nutsedge. In skincare, it's used for its antioxidant and soothing properties, meaning it may help protect skin from environmental stress and calm minor irritation. However, most of the research on this plant has been done in labs or on animals, not directly on human skin, so its benefits in a cream or serum are not yet fully proven.

What it is
An extract derived from the fruit of Cyperus rotundus, a perennial plant native to Africa, Asia, and southern Europe. The plant has a long history in traditional medicine, but its use in modern cosmetics is relatively new.
How it works
The extract contains compounds like flavonoids and polyphenols that can neutralize free radicals, potentially reducing oxidative stress on the skin. It may also have anti-inflammatory effects, helping to calm redness or sensitivity when applied topically.
Pros

Cons and cautions
Limited research
Most studies are lab-based or on animals; there is little clinical evidence proving its effectiveness on human skin.
