What Is Nasturtium Officinale Leaf Extract?
Nasturtium officinale leaf extract is derived from watercress, a leafy plant in the Brassicaceae family. The extract contains bioactive compounds including minerals (potassium, calcium, magnesium, zinc) and phytochemicals that give it antioxidant and anti-inflammatory properties.
In skincare formulations, this ingredient typically serves as a skin conditioner and fragrance component. It is used in small concentrations to support the overall conditioning profile of a product rather than as a primary active ingredient.
How It Works
Nasturtium officinale extract appears to work through multiple mechanisms. Research in animal models suggests it can modulate inflammatory pathways, particularly through glucocorticoid receptor signalling and NF-κB suppression, both key routes involved in skin inflammation.
The extract's bioactive compounds also provide antioxidant benefits, which may help reduce oxidative damage that contributes to skin irritation and premature ageing. The mineral profile supports general skin health, though these effects are modest at typical product concentrations.
Clinical Evidence & References
Research in mice has shown that nasturtium officinale extract can reduce inflammation from irritant contact dermatitis comparable to dexamethasone, without causing toxicological effects. However, this data comes from animal studies using concentrated extracts applied in controlled conditions.
Human clinical data for this ingredient in topical skincare is limited. While the extract has a long history of traditional use and contains recognised bioactive compounds, more research is needed to establish its efficacy and optimal concentrations in cosmetic formulations. It is best viewed as a supportive ingredient rather than a primary treatment for inflammatory skin conditions.

How to Use
Nasturtium officinale extract is typically included in formulations at low concentrations as part of a broader ingredient blend. There are no specific usage restrictions; use products containing this ingredient as directed. If you have known sensitivity to plants in the Brassicaceae family (including cabbage, broccoli, or mustard), patch test first.
