Ingredient review
Cordyceps & Plum Ferment
INCI: CORDYCEPS MILITARIS/PRUNUS MUME FRUIT/SUCROSE FERMENT FILTRATE
A gentle fermented ingredient that may help protect skin from environmental stress, but research is still early.
In plain English
This ingredient is made by fermenting cordyceps mushroom and Japanese apricot (ume) fruit with sugar. The fermentation process creates a liquid rich in amino acids, peptides, and antioxidants. In skincare, it's used to help soothe and protect the skin from daily stressors like pollution and UV exposure. Because it's fermented, it's generally very gentle and well-tolerated, even by sensitive skin types.

Quick decision guide
Useful, but context matters
Cordyceps & Plum Ferment 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 Cordyceps & Plum Ferment.
- 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 filtrate derived from cordyceps militaris (a type of medicinal mushroom) and prunus mume (Japanese apricot) fruit, using sucrose as a fermentation substrate. The resulting liquid contains bioactive compounds such as polysaccharides, organic acids, and phenolic antioxidants.
How it works
The fermentation process breaks down larger molecules into smaller, more easily absorbed ones. The resulting filtrate provides antioxidant activity that helps neutralize free radicals, and may support the skin's natural barrier function by providing amino acids and other nutrients that skin cells can use for repair and maintenance.
Pros
Gentle antioxidant
Provides antioxidant benefits without common irritants, making it suitable for sensitive skin.
Nutrient-rich
Fermentation creates a complex mix of amino acids and peptides that can nourish the skin.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; human skincare trials are scarce.
Variable quality
The potency of the ferment depends heavily on the fermentation process and raw material quality.
Best for
- Anyone looking for a gentle antioxidant ingredient
- People with sensitive or reactive skin who want extra protection
- Those interested in fermented skincare for its nutrient-rich profile
Use caution if
- Individuals with a known allergy to cordyceps or other medicinal mushrooms
Usage tips
Safety summary
This ingredient is considered safe for topical use. The fermentation process reduces potential irritants. Allergic reactions are very rare but possible in individuals with specific mushroom allergies.
Research notes
Research on cordyceps and prunus mume individually shows antioxidant and anti-inflammatory activity in lab studies. However, specific clinical trials on this combined ferment filtrate in human skin are lacking. Evidence is emerging.
Common label clues
- Typical concentration
- Typically 0.5–5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when produced under good manufacturing practices. Not a drug ingredient.
- Common uses
- Serums, Essences, Moisturizers, Sheet masks
- Environmental note
- Cordyceps militaris is typically cultivated, not wild-harvested, making it a more sustainable mushroom source. Prunus mume is a common fruit tree in East Asia.
Good to know
- Fermented ingredients are often pre-digested by microorganisms, which can make them more bioavailable to the skin.
- Cordyceps has a long history in traditional Chinese medicine, but its cosmetic use is relatively new.
