Ingredient review
Wine Ferment Filtrate
INCI: LACTOBACILLUS/WINE EXTRACT FERMENT FILTRATE
A fermented wine extract that may help brighten and protect skin, but research is still limited.
In plain English
This ingredient is made by fermenting wine extract with friendly bacteria (Lactobacillus). The fermentation process creates a liquid rich in antioxidants and gentle acids that can help soften and brighten skin. It's similar to other fermented skincare ingredients like kombucha or sake filtrates, but with a unique wine-derived profile. Think of it as a gentle, probiotic-inspired skin tonic.

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 wine extract with Lactobacillus bacteria. The fermentation breaks down wine compounds into smaller, potentially more skin-friendly molecules, and the final liquid is filtered to remove solids.
How it works
The fermentation process produces natural peptides, organic acids (like lactic acid), and antioxidants (like resveratrol from grapes). These components can gently exfoliate dead skin cells, support the skin's natural barrier, and neutralize free radicals from environmental stressors.
Pros
Antioxidant potential
Grape-derived compounds like resveratrol may help protect skin from environmental damage, though the concentration in the filtrate can vary.
Gentle exfoliation
Natural fermentation acids can help soften and smooth skin without the harshness of stronger chemical exfoliants.
Cons and cautions
Limited research
Most evidence comes from studies on individual grape or fermentation components, not this specific filtrate. More human trials are needed.
Potential allergen
If you have a wine or grape allergy, this ingredient could cause irritation. Always patch test first.
Best for
- Those looking for a gentle, antioxidant-rich toner or essence
- People interested in probiotic or fermented skincare
Use caution if
- Individuals with known allergies to grapes, wine, or fermented products
Usage tips
Safety summary
Considered safe for topical use in cosmetics. The fermentation process is controlled, and the final filtrate is filtered to remove bacteria. However, those with grape or wine allergies should avoid it.
Research notes
Research on this specific ingredient is limited. Studies on grape extracts and fermentation byproducts suggest antioxidant and mild exfoliating benefits, but more direct evidence is needed.
