What it is
An extract derived from the fruiting body (the visible part) of Auricularia polytricha, a jelly fungus commonly known as wood ear or black fungus. It is rich in polysaccharides, particularly beta-glucans, which are known for their water-binding and soothing properties.
How it works
The polysaccharides in wood ear mushroom extract form a thin, flexible film on the skin that helps lock in moisture and reduce water loss. These compounds also interact with skin cells to support a healthy barrier and may calm inflammatory responses, leading to less visible redness or irritation.
Pros
Gentle hydration
Provides moisture without irritation, making it suitable for sensitive skin types.
Soothing potential
May help calm redness and inflammation, offering relief for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; large-scale human trials are lacking.
Variable quality
The extract's potency depends on how it's processed, so not all products deliver the same benefits.
Best for
- People with dry or dehydrated skin looking for a gentle humectant
- Those with sensitive or easily irritated skin who want a soothing ingredient

Use caution if
- Individuals with a known allergy to mushrooms or fungi should patch test first
