What it is
An extract derived from the seeds of Tropaeolum majus, commonly known as garden nasturtium. The seeds contain various bioactive compounds, including flavonoids and glucotropaeolin, which are thought to contribute to its antioxidant and soothing effects.
How it works
The flavonoids in nasturtium seed extract act as antioxidants, meaning they can neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. Additionally, some compounds in the extract may have mild anti-inflammatory properties, helping to calm redness or irritation. It works on the skin's surface and in the upper layers to provide a protective effect.
Pros
Gentle on Skin
Nasturtium seed extract is unlikely to cause irritation, making it a safe choice for sensitive skin or those new to antioxidants.
Natural Sourcing
Derived from a common garden plant, it appeals to consumers looking for plant-based, recognizable ingredients in their skincare.
Cons and cautions
Limited Research
Most evidence for its benefits comes from lab studies or traditional use, not large human clinical trials, so its real-world effects are less certain.
Variable Potency
As a natural extract, its active compound levels can vary between batches, leading to inconsistent performance in different products.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- People with sensitive or reactive skin who want to avoid harsh ingredients
Use caution if
- Those seeking a proven, high-potency antioxidant for anti-aging (consider vitamin C or ferulic acid instead)
Usage tips
Safety summary
Nasturtium seed extract is considered safe for topical use in cosmetics at typical concentrations. It has a low risk of irritation or allergic reaction, though as with any plant extract, individual sensitivity is possible. Always patch test if you have known plant allergies.
Research notes
Research on nasturtium seed extract in skincare is still emerging. In vitro studies suggest antioxidant and anti-inflammatory activity, but there are few published human trials specifically evaluating its cosmetic benefits. Most evidence is extrapolated from traditional use and laboratory data.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions beyond standard cosmetic ingredient regulations.
- Common uses
- Serums, Moisturizers, Toners, Eye Creams
- Environmental note
- Nasturtium is easy to cultivate and not considered an endangered plant, making its sourcing relatively sustainable. However, check for organic or wild-harvested claims if environmental impact is a concern.
Good to know
- Nasturtium is also known as Indian cress and is edible—the flowers and leaves are sometimes used in salads.
- The extract is often combined with other antioxidants in formulations for a synergistic effect.
