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

Gentle antioxidant

Provides a mild antioxidant boost that can help protect skin from daily environmental damage without causing irritation.

Soothing potential

May help calm redness and minor inflammation, making it a good option for sensitive skin types.

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.

Allergy risk

As a plant extract, it can cause allergic reactions in some individuals, especially those with plant allergies.

  • People looking for a gentle, natural antioxidant ingredient
  • Those with sensitive or easily irritated skin who want a soothing addition to their routine

Use caution if

  • Individuals with known allergies to Mirabilis jalapa or related plants (Nyctaginaceae family)

Usage tips

Look for this extract in serums or moisturizers formulated with other antioxidants for a synergistic effect.
Patch test before first use, especially if you have sensitive skin or plant allergies.

Safety summary
