What is Evernia Prunastri (Ring Lichen) Extract?

Evernia Prunastri Extract derives from the lichen Evernia prunastri, commonly known as ring lichen or oakmoss, which grows on oak trees and other bark surfaces in temperate regions. This botanical extract is obtained through solvent extraction, yielding a substance rich in aromatic compounds that contribute to chypre and woody fragrance profiles in perfumery. In cosmetics, it primarily serves in the fragrance category, imparting an earthy, mossy scent character essential for complex olfactory compositions. It functions by releasing volatile molecules that shape product aroma, while also acting as a masking agent to neutralize off-odors from other ingredients. Additionally, its emollient properties provide mild skin conditioning, helping to maintain surface suppleness through humectant-like effects. Though natural, its use is regulated due to specific sensitizing components identified in official cosmetic ingredient databases.
