Ingredient review
Usnea Filipendula Extract
INCI: Usnea Filipendula Extract
Usnea Filipendula Extract is a natural lichen extract with promising antimicrobial activity, but research on its cosmetic benefits is still limited.
In plain English
Usnea Filipendula Extract comes from a type of lichen that grows on trees and rocks, often called beard lichen. In skincare, it's used because it may help fight certain bacteria on the skin, which could be useful for people with acne or other blemish-prone skin. However, there isn't a lot of research yet on how well it works in creams and lotions, so it's considered an emerging ingredient.

What it is
Usnea Filipendula Extract is a natural extract derived from a fruticose lichen of the Usnea genus, known for its traditional use in herbal medicine for its antimicrobial properties.
