Ingredient review
Botrytis Ferment Extract
INCI: Botrytis Ferment Extract Filtrate
A gentle, antioxidant-rich ferment that may help soothe and protect skin, but research is still early.
In plain English
This ingredient is made by fermenting a fungus called Botrytis cinerea (the same one that creates noble rot in grapes for sweet wine). The fermentation process produces a liquid rich in antioxidants and amino acids that can help calm irritation and defend skin against environmental stress. It's a mild, biotech-derived ingredient that fits well into soothing or anti-aging formulas.

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 from the fermentation of Botrytis cinerea, a fungus used in winemaking, processed to extract beneficial compounds for skincare.
How it works
The ferment filtrate contains antioxidants that neutralize free radicals, plus amino acids and peptides that support skin barrier function and reduce visible signs of stress.
Pros
Gentle antioxidant
Provides antioxidant protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm redness and support skin recovery after environmental exposure.
Cons and cautions
Limited evidence
Most benefits are based on lab studies or small trials; large-scale human research is lacking.
Fungal origin
Rare allergic reactions possible in people with mold sensitivities, though generally well-tolerated.
Best for
- People with dull or stressed skin looking for antioxidant support
- Those who enjoy fermented skincare ingredients and want a gentle option
Use caution if
- Anyone with a known allergy to molds or fungi
- Those seeking proven anti-aging results from well-studied ingredients
Usage tips
Safety summary
Considered safe for most skin types at typical use levels. Patch test if you have a known mold allergy. No significant irritation or comedogenic concerns reported.
Research notes
Evidence is emerging, with in vitro studies showing antioxidant and anti-inflammatory activity. Human studies are limited, so benefits are suggestive rather than proven.
Common label clues
- Typical concentration
- 1-5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions.
- Common uses
- Serums, Moisturizers, Anti-aging creams
- Environmental note
- Produced via controlled fermentation, which is a low-impact, sustainable process compared to extraction from wild plants.
Good to know
- Botrytis cinerea is the same fungus used to make Sauternes wine, giving it a unique origin story.
- Fermented ingredients like this are often pre-digested by microbes, which can make them more easily absorbed by skin.
