Ingredient review
Silk Tree Bark Extract
INCI: Albizia Julibrissin Bark Extract
A gentle botanical extract that may help calm skin and fight free radicals, but research is still early.
In plain English
Silk tree bark extract comes from the bark of the Albizia julibrissin tree, also called the mimosa or Persian silk tree. In skincare, it's used to soothe irritation and protect skin from environmental damage because it contains compounds that can calm redness and fight off free radicals (unstable molecules that can harm skin cells). Think of it as a gentle, plant-based helper for sensitive or stressed skin.
