In plain English

This ingredient is made by fermenting a type of mushroom called Agrocybe cylindracea (also known as black poplar mushroom). The fermentation process breaks down the mushroom's compounds, creating a liquid filtrate rich in antioxidants and other beneficial molecules. In skincare, it's used to help soothe the skin and defend against damage from pollution and UV exposure, similar to how other mushroom ferments work.

Quick decision guide

Useful, but context matters

Agrocybe Cylindracea Ferment Filtrate 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 Agrocybe Cylindracea Ferment Filtrate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 from the Agrocybe cylindracea mushroom, a species known for its high content of polysaccharides, peptides, and phenolic compounds with antioxidant activity.

How it works

The fermentation process releases bioactive compounds from the mushroom, which can help neutralize free radicals (unstable molecules that damage skin cells) and reduce signs of inflammation. It may also support the skin's natural barrier function by providing moisture and soothing irritation.

Pros

Gentle antioxidant

Provides antioxidant protection without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.

Soothing potential

The fermentation process may produce compounds that help calm redness and inflammation, offering a mild soothing effect for everyday use.

Cons and cautions

Limited research

Most evidence comes from lab studies or traditional use; there are few human clinical trials confirming its specific benefits in skincare.

Variable quality

The potency and effectiveness depend heavily on the fermentation method and mushroom strain used, which can vary between brands.

Best for

  • People with sensitive or reactive skin looking for gentle antioxidant support
  • Those interested in fermented skincare ingredients for their potential skin-soothing benefits

Use caution if

  • Individuals with known mushroom allergies should patch test first
  • Those seeking proven, high-evidence ingredients may prefer better-studied antioxidants like vitamin C or niacinamide

Usage tips

Use in a serum or essence after cleansing and before moisturizer for best absorption
Pair with other antioxidants like vitamin E or ferulic acid for enhanced protection
Store products containing this ingredient in a cool, dark place to preserve its activity

Safety summary

Agrocybe cylindracea ferment filtrate is considered safe for topical use with a low risk of irritation or allergy. As with any new ingredient, a patch test is recommended for those with sensitive skin or mushroom allergies.

Research notes

Research on this specific ferment is limited. Studies on related mushroom ferments (e.g., Reishi, Shiitake) show antioxidant and anti-inflammatory activity in lab settings, but direct human data for Agrocybe cylindracea is sparse.

Common label clues

Typical concentration
Typically used at 1-5% in leave-on products
Regulatory status
Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions beyond standard cosmetic safety requirements.
Common uses
Serums, Moisturizers, Essences
Environmental note
Mushroom cultivation has a relatively low environmental footprint compared to many plant crops, and fermentation is a sustainable processing method.

Good to know

  • Fermented ingredients are often more easily absorbed by the skin due to the smaller molecular size of the compounds
  • This mushroom is also known as the black poplar mushroom and is edible in some cuisines
