Ingredient review
Fermented Mushroom & Artemisia Complex
INCI: HERICIUM ERINACEUS/LACTOBACILLUS/LEUCONOSTOC/ARTEMISIA CAPILLARIS LEAF/STEM FERMENT FILTRATE
A fermented blend of lion's mane mushroom and mugwort that may help calm skin and support a healthy moisture barrier, though human studies are limited.
In plain English
This ingredient is made by fermenting lion's mane mushroom and mugwort (a type of herb) with friendly bacteria. The fermentation process breaks down the plant materials into smaller, potentially more skin-friendly compounds. It's used in skincare to help soothe irritation and keep the skin's outer layer healthy, but most of the evidence comes from lab studies rather than large human trials.

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 lion's mane mushroom (Hericium erinaceus) and mugwort (Artemisia capillaris) with Lactobacillus and Leuconostoc bacteria. The fermentation creates a liquid rich in peptides, polysaccharides, and other bioactive compounds.
How it works
The fermentation process produces smaller molecules that may be better absorbed by the skin. The mushroom and mugwort components are thought to have antioxidant and anti-inflammatory properties, potentially helping to calm redness and support the skin's natural barrier function.
Pros
Gentle soothing potential
The fermentation process may create compounds that help calm redness and irritation without harsh chemicals.
Barrier-friendly
Polysaccharides from the mushroom may help support the skin's moisture barrier, keeping hydration locked in.
Cons and cautions
Limited human research
Most evidence comes from lab or animal studies; large-scale human trials are lacking, so effectiveness is not fully proven.
Potential for sensitivity
Fermented ingredients can sometimes cause reactions in people with very reactive skin or mold allergies.
Best for
- People with sensitive or easily irritated skin
- Those looking for gentle, fermented skincare ingredients
Use caution if
- Individuals with known allergies to mushrooms or mugwort
- Anyone with a history of severe allergic reactions to fermented ingredients
Usage tips
Safety summary
This ingredient is considered safe for topical cosmetic use based on its history of use and the generally low toxicity of its components. However, individual allergies to mushrooms or mugwort are possible. Always patch test.
Research notes
Research on Hericium erinaceus and Artemisia capillaris shows antioxidant and anti-inflammatory activity in lab studies. Fermentation may enhance these properties, but direct clinical evidence for this specific ferment blend in skincare is still emerging.
