What it is
A post-fermentation filtrate created by fermenting Artemisia princeps (mugwort) leaf oil with Kluyveromyces yeast and Lactobacillus bacteria. The fermentation process produces a liquid rich in peptides, organic acids, and plant-derived compounds.
How it works
The fermentation process generates bioactive molecules that may help calm skin inflammation and support the growth of beneficial skin bacteria. The filtrate also contains natural antioxidants from mugwort, which can help protect skin from environmental stress.
Pros
Gentle soothing potential
The fermentation process may enhance the calming properties of mugwort, making it a good option for those with redness or sensitivity.
Microbiome-friendly
Probiotic ferments like this one can help maintain a healthy balance of skin bacteria, which is important for overall skin health.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use of mugwort, not large human trials on this specific ferment filtrate.
Potential allergen
Mugwort is a known allergen for some people, especially those with hay fever or plant allergies, so patch testing is wise.
Best for
- People with sensitive or reactive skin looking for gentle soothing ingredients
- Those interested in microbiome-friendly skincare
Use caution if
- Individuals with a known allergy to mugwort or related Asteraceae plants
