What it is
Evernia Furfuracea Extract, known as treemoss, is obtained from a lichen that grows on trees and is a classic raw material in perfumery. In cosmetics it is used as a fragrance ingredient, prized for its deep, woody, earthy aroma. It is added at low levels to build scent rather than for any functional skin benefit.
Safety & warnings
Treemoss is a recognized fragrance allergen and a known contact sensitizer; it must be declared on EU labels above set thresholds and is subject to industry restrictions on its allowable level. It can contain sensitizing constituents such as atranol and chloroatranol, so individuals with fragrance allergies or sensitive skin should be cautious.

History
