Ingredient review
Fermented Broccoli Extract
INCI: LACTOBACILLUS/LEUCONOSTOC/BROCCOLI EXTRACT FERMENT FILTRATE
A gentle, fermented broccoli extract that may help calm and protect skin with antioxidants, though research is still emerging.
In plain English
This ingredient is made by fermenting broccoli with beneficial bacteria (Lactobacillus and Leuconostoc). The fermentation process breaks down the plant material, potentially making its antioxidants and nutrients easier for skin to absorb. It's used in skincare for its soothing and protective properties, similar to how eating fermented foods can support gut health.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A filtrate obtained after fermenting broccoli extract with Lactobacillus and Leuconostoc bacteria. This process creates a blend of bioactive compounds, including peptides, vitamins, and antioxidants from the broccoli, plus metabolites from the bacteria.
How it works
The fermentation breaks down broccoli's cell walls, releasing antioxidants like sulforaphane and vitamin C. These compounds help neutralize free radicals that cause premature aging. The bacterial metabolites may also support the skin's microbiome and reduce inflammation, leading to a calmer, more balanced complexion.
Pros
Gentle antioxidant
Fermentation may enhance the bioavailability of broccoli's antioxidants, offering protection without harshness.
Microbiome-friendly
The bacterial ferment may help maintain a balanced skin microbiome, which is key for a healthy complexion.
Cons and cautions
Limited research
Most evidence comes from lab studies or ingredient supplier data; independent human trials are scarce.
Potential allergen
People with broccoli or cruciferous vegetable allergies may react, though this is rare.
Best for
- People looking for gentle antioxidant protection
- Those with sensitive or reactive skin seeking soothing ingredients
Use caution if
- Individuals with known allergies to broccoli or cruciferous vegetables
- Anyone with a very compromised skin barrier should patch test first
Usage tips
Safety summary
Considered safe for topical use with a low risk of irritation. As with any new ingredient, a patch test is recommended for those with sensitive skin or allergies.
