What it is
Brussels sprout extract is a botanical ingredient obtained from the immature buds of Brassica oleracea (the same species as cabbage and kale). It is rich in glucosinolates, flavonoids, and vitamin C, which contribute to its antioxidant and soothing properties.
How it works
In skincare, Brussels sprout extract works primarily by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It also provides a mild anti-inflammatory effect, which can help calm redness and irritation. The extract is typically added to water-based formulas and works best when combined with other antioxidants.
Pros
Gentle on skin
Brussels sprout extract has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Natural antioxidant source
It provides a plant-derived way to help protect skin from free radical damage, which can contribute to premature aging.
Cons and cautions
Limited research
Most studies on Brussels sprout benefits focus on oral consumption, not topical application. Its effectiveness in skincare is not yet well-established.
Variable potency
The concentration of active compounds can vary widely depending on growing conditions and extraction methods, leading to inconsistent results.
Best for
- Anyone looking for a gentle, plant-based antioxidant
- People with sensitive or easily irritated skin who want extra protection
Use caution if
- Individuals with a known allergy to Brassicaceae family plants (e.g., broccoli, cabbage)
