Hairy Bracket Mushroom Extract
INCI: Trametes hirsuta extract
A mushroom extract with antioxidant potential that may help calm skin, though research is still early.
In plain English
This ingredient comes from a type of mushroom called Trametes hirsuta, also known as hairy bracket fungus. In skincare, it is used to provide antioxidant benefits, meaning it can help protect your skin from damage caused by environmental stressors like pollution and UV rays. It may also have soothing properties, which can be helpful for irritated or sensitive skin. However, the research on this specific mushroom extract in cosmetics is still limited, so its effects are not as well-documented as more common ingredients like vitamin C or green tea.

What it is
Trametes hirsuta extract is a natural ingredient derived from the fruiting body of the Trametes hirsuta mushroom, a fungus that grows on dead wood. It contains bioactive compounds such as polysaccharides and triterpenoids, which are thought to contribute to its antioxidant and anti-inflammatory activity.
How it works
In a cosmetic product, Trametes hirsuta extract works primarily by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its polysaccharides may also form a protective film on the skin, helping to retain moisture and reduce irritation. The exact mechanisms are still being studied, but early research suggests it can support the skin's natural defense systems.
Pros
Natural antioxidant
Helps protect skin from free radical damage caused by pollution and UV exposure, which can lead to premature aging.
Soothing potential
May calm redness and irritation, making it a gentle option for sensitive skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human trials, so its real-world benefits are not fully confirmed.
Rare allergy risk
People with mushroom allergies could experience a reaction, though this is uncommon in topical use.
Best for
- People looking for natural antioxidant ingredients
- Those with sensitive or easily irritated skin seeking soothing options
Use caution if
- Individuals with known allergies to mushrooms or fungi
Usage tips
Safety summary
