What it is
A natural extract blend combining the root of Wasabia japonica (Japanese horseradish) with sprouts from various Brassica species, including mustard, cabbage, broccoli, cauliflower, and kale. These plants are rich in compounds called glucosinolates and isothiocyanates, which are known for their antioxidant and anti-inflammatory properties.
How it works
The isothiocyanates in wasabi and brassica sprouts help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. They also appear to inhibit certain enzymes that contribute to inflammation, potentially reducing redness and irritation. In a cosmetic product, this extract works to support the skin's natural defense system against environmental aggressors.
Pros
Rich in antioxidants
Contains isothiocyanates that help neutralize free radicals, protecting skin from pollution and UV-induced damage.
Soothing potential
May reduce redness and calm irritation, making it a good option for sensitive skin types when formulated properly.
Cons and cautions
Limited research on skin
Most studies focus on oral consumption of wasabi or brassica compounds; direct evidence for topical benefits in humans is still emerging.
Potential allergen risk
As a plant extract, it may cause allergic reactions in people sensitive to mustard or cabbage family plants.
Best for
- People looking for antioxidant protection from a natural source
- Those with normal to combination skin who want a gentle, plant-based ingredient
Use caution if
- Individuals with known allergies to wasabi or brassica vegetables
- Those with extremely reactive skin who may react to botanical extracts
Usage tips
Safety summary
This extract is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible in individuals with sensitivities to mustard or cabbage family plants. Always patch test new products.
Research notes
Research on wasabi and brassica sprouts focuses on their antioxidant and anti-inflammatory properties, primarily from in vitro and animal studies. Human studies on topical application are limited, but the compounds are well-studied in oral health and nutrition contexts.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used within recommended concentrations. Not a regulated drug ingredient.
- Common uses
- Serums, Moisturizers, Eye creams
- Environmental note
- Sourcing of wasabi and brassica sprouts is generally sustainable, though true wasabi (Wasabia japonica) is rare and often substituted with horseradish in food; in cosmetics, the plant is typically cultivated for extract purposes.
Good to know
- The extract is often produced from sprouted seeds, which may have higher concentrations of beneficial compounds than mature plants.
- Wasabi and brassica sprouts are also studied for their potential anti-aging effects due to their ability to support collagen integrity.
