Fermented Cordyceps & Lilyturf Root Extract

INCI: LACTOBACILLUS/CORDYCEPS MILITARIS/OPHIOPOGON JAPONICUS ROOT EXTRACT FERMENT FILTRATE

A fermented botanical extract that may help soothe and condition skin, but research is still early and benefits are not guaranteed.

beautyskincareferment

In plain English

This ingredient is made by fermenting two plants—Cordyceps militaris (a type of medicinal mushroom) and Ophiopogon japonicus (a root also called lilyturf or mondo grass)—with friendly bacteria (Lactobacillus). The fermentation process breaks down the plant materials into smaller, potentially more absorbable compounds like amino acids, peptides, and antioxidants. In skincare, it's used to help keep skin feeling smooth, hydrated, and calm. Think of it as a gentle, nutrient-rich broth for your skin.

Quick decision guide

Useful, but context matters

Fermented Cordyceps & Lilyturf Root 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Fermented Cordyceps & Lilyturf Root Extract.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A fermented filtrate derived from the roots of Cordyceps militaris and Ophiopogon japonicus, cultured with Lactobacillus bacteria. The fermentation process is intended to enhance the bioavailability of the plants' natural compounds.

How it works

The fermentation breaks down larger plant molecules into smaller ones, which may help them penetrate the skin more easily. The resulting filtrate contains amino acids, sugars, and antioxidant compounds that can support the skin's natural barrier and provide mild hydration. It also has potential anti-inflammatory properties due to the presence of polysaccharides and flavonoids from the original plants.

Pros

Gentle conditioning

The fermentation process creates a mild, nutrient-rich filtrate that can help soften and smooth skin without irritation for most users.

Antioxidant support

Contains compounds from Cordyceps and Ophiopogon that may help neutralize free radicals, potentially reducing oxidative stress on the skin.

Cons and cautions

Limited evidence

Most research on Cordyceps and Ophiopogon is from lab or animal studies; human skin studies on this specific ferment are scarce, so benefits are not proven.

Potential for sensitivity

Fermented ingredients can sometimes cause reactions in people with very reactive skin or those allergic to molds or fungi.

Best for

  • Anyone looking for a gentle, antioxidant-rich skin conditioner
  • Those interested in fermented skincare ingredients
  • People with normal to dry skin seeking extra hydration

Use caution if

  • Individuals with known allergies to Cordyceps or Ophiopogon
  • Those with very sensitive skin who react to fermented ingredients

Usage tips

Use after cleansing and before heavier creams to allow the ferment to absorb.
Pair with a simple moisturizer to lock in hydration and support the skin barrier.
Patch test on your inner arm before first full-face use, especially if you have sensitive skin.

Safety summary

This ingredient is considered safe for topical use in cosmetics at typical concentrations. The fermentation process is controlled to prevent contamination. Allergic reactions are rare but possible, especially in individuals with mold or fungus sensitivities.

Research notes

Research on Cordyceps militaris and Ophiopogon japonicus individually shows antioxidant and anti-inflammatory activity in lab studies. However, there are no published clinical trials on this specific fermented blend for skin benefits. The evidence is emerging and largely based on traditional use and preliminary science.

Common label clues

Typical concentration
1–5% in leave-on products
Regulatory status
Generally recognized as safe for cosmetic use in the EU, US, and Korea. No specific restrictions.
Common uses
Serums, Essences, Moisturizers, Sheet masks
Environmental note
Cordyceps militaris is cultivated rather than wild-harvested, making it a more sustainable source. Ophiopogon japonicus is widely grown in East Asia.

Good to know

  • This ingredient is often found in Korean and Japanese skincare products that emphasize fermentation.
  • The 'filtrate' means the solid plant material is removed after fermentation, leaving only the liquid rich in active compounds.
