What it is
Chaga mushroom extract is derived from the sclerotium (a hard, protective mass) of the Fusco poria obliqua fungus, commonly known as chaga. It is rich in melanin, beta-glucans, and other polyphenols that give it antioxidant and anti-inflammatory properties.
How it works
In a cosmetic product, chaga mushroom extract works by neutralizing free radicals—unstable molecules that can damage skin cells and accelerate aging. Its beta-glucans may also help support the skin's moisture barrier and reduce redness or irritation by calming inflammatory responses.
Pros
Rich in antioxidants
Chaga contains high levels of melanin and polyphenols that help protect skin from free radical damage caused by pollution and UV rays.
Gentle and soothing
Its anti-inflammatory properties can help calm redness and irritation, making it suitable for sensitive skin types.
Cons and cautions
Limited research
Most evidence for chaga's skin benefits comes from lab studies, not large human trials, so its effectiveness is not fully proven.
Potential allergen
People with mushroom or fungal allergies may experience a reaction, so patch testing is recommended.
Best for
- People with dull or stressed skin looking for antioxidant support
- Those with sensitive or easily irritated skin seeking a gentle soothing ingredient
Use caution if
- Individuals with known allergies to mushrooms or fungi
Usage tips
Safety summary
