What it is
An extract derived from the flowers of Tropaeolum majus, commonly known as nasturtium or Indian cress. The flowers are rich in flavonoids, vitamin C, and other antioxidant compounds.
How it works
The flavonoids and other polyphenols in nasturtium flower extract act as antioxidants, neutralizing free radicals that can cause oxidative stress and premature aging. It also has mild anti-inflammatory properties that may help reduce redness and soothe sensitive skin.
Pros
Gentle soothing potential
Nasturtium extract may help calm redness and irritation, making it a good option for sensitive skin types that react to stronger botanicals.
Antioxidant support
Its flavonoid content helps protect skin from free radical damage, which can contribute to premature aging over time.
Cons and cautions
Limited research on skin
Most evidence comes from lab studies or traditional use; there are few well-controlled human trials confirming its benefits in skincare.
Allergy risk
As a plant extract, it can cause allergic reactions in people sensitive to the Brassicaceae family (mustard, cabbage, etc.). Patch testing is recommended.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Anyone wanting to add a mild antioxidant to their routine without strong actives
Use caution if
- Individuals with known allergies to nasturtium or related plants (Brassicaceae family)
