Ingredient review
Fermented Artemisia Annua Extract
INCI: LACTOBACILLUS/LEUCONOSTOC/ARTEMISIA ANNUA EXTRACT/POLYSORBATE 80 FERMENT LYSATE FILTRATE
A fermented botanical extract with potential antioxidant and soothing properties, but research on its topical benefits is still emerging.
In plain English
This ingredient is made by fermenting sweet wormwood (Artemisia annua) with beneficial bacteria (Lactobacillus and Leuconostoc). The fermentation process may break down the plant material into smaller, potentially more absorbable compounds. It's used in skincare for its possible antioxidant and calming effects, though most evidence comes from traditional use and lab studies rather than large human trials.

Quick decision guide
Useful, but context matters
Fermented Artemisia Annua 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 Fermented Artemisia Annua 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 lysate filtrate of Artemisia annua extract, processed with Lactobacillus and Leuconostoc bacteria and stabilized with Polysorbate 80. The fermentation is intended to enhance the bioavailability of the plant's active compounds.
How it works
The fermentation process may release and modify bioactive compounds from Artemisia annua, such as artemisinin and flavonoids. These compounds are thought to help neutralize free radicals (antioxidant activity) and reduce signs of skin irritation or redness (soothing effect). The lysate filtrate form means the bacterial cells are broken down and removed, leaving only the fermented plant extract.
Pros
Potential antioxidant benefits
Artemisia annua contains flavonoids and other compounds that may help protect skin from oxidative stress caused by UV and pollution.
Soothing properties
Traditional use and some lab studies suggest it can help reduce redness and calm irritated skin, making it a good option for sensitive skin types.
Cons and cautions
Limited research on topical use
Most studies focus on oral or internal use of Artemisia annua; evidence for its benefits in skincare is still emerging and not yet robust.
Contains Polysorbate 80
This emulsifier can be irritating for some people with very sensitive or compromised skin, though it's generally considered safe at low concentrations.
Best for
- Those with normal to combination skin looking for antioxidant support
- People interested in fermented skincare ingredients
Use caution if
- Individuals with known allergies to Artemisia (ragweed family) or Polysorbate 80
Usage tips
Safety summary
This ingredient is considered safe for topical use in cosmetics at typical concentrations. The main caution is for individuals with allergies to the Asteraceae (ragweed) family or those sensitive to Polysorbate 80. Always patch test.
Research notes
Research on topical Artemisia annua is limited. Most evidence comes from in vitro studies showing antioxidant and anti-inflammatory activity. Human studies are needed to confirm efficacy in skincare.
Common label clues
- Typical concentration
- Typically 1-5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as directed. Not approved for medical claims.
- Common uses
- Serums, Toners, Moisturizers
- Environmental note
- Artemisia annua is a widely cultivated plant; fermentation processes are generally considered low-impact, but Polysorbate 80 is synthetic and may have environmental persistence concerns.
Good to know
- Fermented ingredients are often marketed as 'prebiotic' or 'postbiotic' skincare, but the actual benefits on skin microbiome are still being studied.
- Artemisia annua is also known as sweet wormwood and has a long history in traditional Chinese medicine.
