Ingredient review
Alnus Firmifolia Fruit Extract
INCI: Alnus Firmifolia Fruit Extract
A gentle antioxidant extract from alder fruit that may help protect skin from environmental stress, though research is still early.
In plain English
Alnus Firmifolia Fruit Extract comes from the fruit of a type of alder tree. In skincare, it's used as a mild antioxidant, meaning it can help neutralize some of the damage caused by things like pollution and UV exposure. Because it's plant-based and generally well-tolerated, it's often found in products for sensitive or normal skin types. However, there isn't a lot of human research yet, so its benefits are mostly based on lab studies and traditional use.

What it is
A natural extract obtained from the fruit of Alnus firmifolia, a tree native to parts of Asia. The extract contains polyphenols and flavonoids, which are compounds known for their antioxidant activity.
How it works
The polyphenols in the extract can donate electrons to neutralize free radicals (unstable molecules that can damage skin cells). This helps reduce oxidative stress on the skin, which may slow signs of aging and calm minor irritation.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without causing irritation, making it suitable for sensitive skin.
Soothing potential
Traditional use and early research suggest it may help calm redness or minor inflammation.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human trials, so its real-world benefits are not fully proven.
Lower potency
Compared to well-studied antioxidants like vitamin C, this extract may offer weaker protection against oxidative damage.
Best for
- Anyone looking for a gentle antioxidant ingredient
- People with sensitive or reactive skin who want extra protection
Use caution if
- Those seeking a proven, high-potency antioxidant with strong clinical backing
