Ingredient review
Piper Retrofactum Fruit Extract
INCI: PIPER RETROFRACTUM FRUIT 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 from a tropical pepper fruit, similar to long pepper. In skincare, it's added for its ability to fight free radicals (unstable molecules that can damage skin) and to help calm irritation. However, most of what we know comes from lab studies, not human trials, so its real-world effects are still being explored.

What it is
A natural extract derived from the dried fruit of Piper retrofactum, a vine native to Southeast Asia. The fruit contains compounds like piperine and flavonoids, which are thought to have antioxidant and anti-inflammatory properties.
How it works
In a cosmetic product, the extract is believed to neutralize free radicals caused by UV exposure and pollution, potentially reducing oxidative stress on the skin. It may also help soothe minor redness or irritation by calming inflammatory pathways, though these effects are not yet confirmed in human skin.
Pros
