What it is
A water- or oil-based extract made from the leaves of Tropaeolum majus, a flowering plant commonly known as nasturtium. The extract contains flavonoids, phenolic acids, and other plant compounds with antioxidant and soothing potential.
How it works
The flavonoids and other polyphenols in nasturtium leaf extract can neutralize free radicals, which are unstable molecules that can damage skin cells. It may also help calm minor redness or irritation by interacting with skin's inflammatory pathways, though the exact mechanism is not fully understood.
Pros
Gentle and soothing
Nasturtium leaf extract is mild enough for sensitive skin and may help calm minor redness without causing irritation.
Natural antioxidant
It provides a plant-based source of antioxidants that can help protect skin from daily environmental damage like pollution.
Cons and cautions
Limited research
There aren't many high-quality human studies proving its effectiveness in skincare, so its benefits are mostly based on lab data and traditional use.
Variable quality
Because it's a natural extract, the potency and purity can differ from product to product, making results less predictable.
Best for
- Anyone looking for a mild, natural antioxidant in their routine
- People with sensitive or easily irritated skin who want gentle soothing ingredients
Use caution if
- Those with known allergies to nasturtium or related plants (Brassicaceae family)
- Anyone seeking a proven, high-potency antioxidant — consider vitamin C or ferulic acid instead
Usage tips

Nasturtium leaf extract is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible, especially in individuals sensitive to plants in the Brassicaceae family (like mustard or cabbage).
Research notes
Most evidence comes from in vitro (lab) studies showing antioxidant and anti-inflammatory activity. Human clinical trials are scarce, so the ingredient's real-world skincare benefits are not yet well-established.
