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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A filtrate obtained after fermenting Lycium chinense (goji berry) fruit with Saccharomyces (a type of yeast). The fermentation creates a liquid rich in peptides, amino acids, and antioxidants.
How it works
The fermentation process breaks down goji berry components into smaller molecules that may be more easily absorbed by the skin. These molecules can help neutralize free radicals and support the skin's natural barrier function.
Pros
Antioxidant-rich
Fermentation may enhance the bioavailability of goji berry's natural antioxidants, helping protect skin from environmental damage.
Gentle conditioning
The ferment filtrate can help soften and smooth skin without heavy oils or synthetic additives.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; large-scale human trials on this specific ferment are scarce.
Potential allergen
Goji berry is a fruit, and yeast is used in fermentation, so individuals with allergies to either should patch test first.
Best for
- People looking for antioxidant-rich skincare
- Those interested in fermented ingredients for skin health
Use caution if
- Individuals with known allergies to goji berries or yeast
- Those with extremely sensitive skin who react to fermented ingredients
Usage tips
Safety summary
