INCI: DAEDALEA DICKINSII MYCELIUM FERMENT FILTRATE

A mushroom-derived ferment that may help calm and protect skin, but research is still early and benefits are not yet proven in human studies.

In plain English

This is a liquid made by fermenting the mycelium (the root-like part) of a mushroom called Daedalea dickinsii. The fermentation process breaks down the mushroom material, creating a filtrate rich in compounds like beta-glucans and antioxidants. In skincare, it's added to products to potentially soothe irritation and defend against environmental stress, though most evidence comes from lab studies rather than human trials.

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 mycelium of Daedalea dickinsii, a wood-rotting mushroom also known as oak mazegill. The mycelium is fermented, then filtered to create a liquid ingredient used in cosmetic formulations.

How it works

The fermentation process releases bioactive compounds such as polysaccharides (beta-glucans) and phenolic antioxidants. These compounds are thought to help calm inflammation and neutralize free radicals on the skin, potentially reducing signs of oxidative stress. However, the exact mechanisms in human skin are not fully understood.

Pros

Gentle antioxidant

The fermentation process creates compounds that may help neutralize free radicals, potentially protecting skin from pollution and UV damage without harsh chemicals.

Soothing potential

Beta-glucans from the mushroom mycelium are known for their calming properties, which may help reduce redness and irritation for some skin types.

Cons and cautions

Limited human evidence

Most research on Daedalea dickinsii is in lab settings or animal models. There are no large human clinical trials proving its benefits for skin.

Potential allergen

As a mushroom-derived ingredient, it may cause allergic reactions in people with mushroom sensitivities. Always patch test before full use.

Best for

  • People with normal to dry skin looking for gentle antioxidant support
  • Those interested in fermented skincare ingredients for their potential soothing benefits

Use caution if

  • Individuals with known mushroom allergies should patch test first
  • Those with extremely sensitive skin may want to start with a low concentration product

Usage tips

Apply products containing this ingredient after cleansing and before heavier creams to maximize absorption.
Store products in a cool, dark place to preserve the stability of the ferment filtrate.
Use consistently for at least 4-6 weeks to assess any visible benefits.

Safety summary

Daedalea dickinsii mycelium ferment filtrate is considered safe for topical use in cosmetics at typical concentrations. The main risk is a potential allergic reaction in individuals with mushroom allergies. As with any new ingredient, patch testing is recommended.

Research notes

Research on this specific ingredient is limited. Laboratory studies suggest antioxidant and anti-inflammatory activity, but human clinical data is lacking. Most evidence comes from studies on related mushroom species or in vitro models.

Common label clues
