Ingredient review
Hydrolyzed Pleurotus Nebrodensis Mycelium Extract
INCI: HYDROLYZED PLEUROTUS NEBRODENSIS MYCELIUM EXTRACT
A gentle mushroom-derived ingredient that may calm irritation and support skin hydration, though research is still emerging.
In plain English
This ingredient comes from the mycelium (the root-like part) of a specific mushroom called Pleurotus nebrodensis, which is then broken down (hydrolyzed) into smaller pieces so the skin can absorb it better. It's thought to help soothe redness and keep the skin feeling hydrated, similar to how some other mushroom extracts work in skincare. Because it's a natural extract, its effects can vary from product to product.

What it is
A water-soluble extract derived from the mycelium of the Pleurotus nebrodensis mushroom, which has been hydrolyzed (broken down) to release beneficial compounds like polysaccharides and beta-glucans.
How it works
The polysaccharides and beta-glucans in the extract are believed to form a thin, soothing film on the skin's surface, which can help reduce the appearance of redness and support the skin's natural moisture barrier. It may also have mild antioxidant properties.
Pros
Gentle on skin
This ingredient is considered very low risk for irritation, making it suitable for sensitive skin types.
Hydrating film
It can help the skin feel softer and more hydrated by forming a light, soothing layer on the surface.
Cons and cautions
Limited research
Most evidence comes from lab studies or related mushroom species; there are few human studies on this exact extract.
Variable potency
As a natural extract, its active compound levels can differ between batches, so results may not be consistent.
Best for
- People with sensitive or easily irritated skin
- Those looking for gentle, natural hydrating ingredients
Use caution if
- Individuals with a known mushroom allergy
- Anyone seeking strong, fast-acting results
