Ingredient review
Streptomyces Gougerotii Ferment Extract
INCI: STREPTOMYCES GOUGEROTII FERMENT EXTRACT
A biotech ferment extract with early research suggesting soothing benefits, but human studies are limited.
In plain English
This ingredient is made by fermenting a specific type of bacteria (Streptomyces gougerotii) in a lab. The resulting extract contains compounds that may help calm irritated skin and support its natural barrier. Because it's produced through fermentation, it's considered a biotech ingredient, not something harvested from nature. While promising, most evidence comes from lab studies, so it's not yet a proven powerhouse in skincare.

Quick decision guide
Useful, but context matters
Streptomyces Gougerotii Ferment Extract is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Streptomyces Gougerotii Ferment Extract.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 fermented extract from the bacterium Streptomyces gougerotii, produced under controlled lab conditions. It contains peptides, enzymes, and other bioactive molecules that may interact with skin cells.
How it works
The extract is thought to reduce the production of pro-inflammatory signals in skin cells, helping to calm redness and irritation. It may also support the skin's natural repair processes by encouraging collagen production and strengthening the barrier.
Pros
Gentle soothing potential
Early research indicates it may reduce skin inflammation, making it a good option for sensitive skin types.
Biotech sustainability
Produced via fermentation, which is generally more sustainable and consistent than harvesting from natural sources.
Cons and cautions
Limited human evidence
Most benefits are based on lab or animal studies; robust human trials are lacking, so effectiveness is not fully proven.
Niche availability
Not widely used in mainstream products, so it can be harder to find and may be more expensive.
Best for
- People with sensitive or reactive skin looking for a gentle soothing ingredient
- Those interested in biotech-derived, sustainable skincare ingredients
Use caution if
- Anyone with a known allergy to fermented ingredients or bacterial extracts (rare)
Usage tips
Safety summary
Based on available data, this ingredient appears safe for topical use at typical cosmetic concentrations. Irritation and allergy risks are low, but long-term safety data in humans is limited.
Research notes
A few in vitro studies suggest anti-inflammatory and collagen-boosting effects, but there are no large-scale human clinical trials. Evidence is emerging and not yet strong.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used at typical concentrations, but not specifically approved by the FDA as a drug ingredient.
- Common uses
- Serums, Moisturizers, Soothing treatments
- Environmental note
- Biotech production via fermentation has a lower environmental footprint compared to wild harvesting, but the energy use of lab facilities should be considered.
Good to know
- Streptomyces bacteria are a common source of antibiotics in medicine, but this extract is used for cosmetic purposes only.
- The fermentation process creates a complex mix of compounds, so the exact active molecules are not always fully identified.
