Ingredient review
Acacia Farnesiana Stem Bark Extract
INCI: Acacia Farnesiana Stem Bark Extract
A gentle botanical extract with antioxidant potential, but research is limited and benefits are not yet well-established in human skin.
In plain English
This is an extract made from the bark of a tree called Acacia farnesiana, also known as sweet acacia. In skincare, it's used mainly for its antioxidant content, which may help protect skin from environmental damage. However, most of the evidence comes from lab studies, not human trials, so it's hard to say how much it actually helps your skin.

What it is
A natural extract derived from the stem bark of the Acacia farnesiana tree, a plant native to tropical and subtropical regions. The bark is dried, ground, and then extracted using a solvent (like water or alcohol) to concentrate its active compounds, such as tannins, flavonoids, and other polyphenols.
How it works
In a cosmetic product, this extract is believed to work as an antioxidant, meaning it can neutralize free radicals (unstable molecules that can damage skin cells). It may also have mild astringent and soothing properties, potentially helping to calm irritated skin. However, these effects are based on limited research and may vary by formulation.
Pros

Cons and cautions
