Mirabilis Jalapa Seed Extract
INCI: MIRABILIS JALAPA SEED EXTRACT
A gentle, plant-based extract with antioxidant potential, but more research is needed to confirm its benefits in skincare.
In plain English
Mirabilis jalapa seed extract comes from the seeds of the four o'clock flower, a plant native to tropical Americas. In skincare, it is used for its antioxidant and soothing properties, meaning it may help protect skin from environmental stress and calm minor irritation.

What it is
An extract derived from the seeds of Mirabilis jalapa, also known as the four o'clock flower or marvel of Peru. The seeds contain compounds like flavonoids and phenolic acids that have antioxidant activity.
How it works
In a cosmetic product, this extract is believed to work by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells). It may also help reduce the appearance of redness by calming inflammatory pathways in the skin, though the exact mechanisms are not fully understood.
Pros

Cons and cautions
Limited research
There are very few peer-reviewed studies on this extract's effects on human skin, so its benefits are not as proven as more common antioxidants.
