Fomes Officinalis (Trunk Rot) Extract
What is Fomes Officinalis (Trunk Rot) Extract?
Fomes officinalis, commonly called larch polypore or agarikon, is a woody bracket fungus that grows primarily on larch and other conifer trees in northern forests, often associated with trunk rot. The extract comes from its hardened fruiting bodies, rich in polysaccharides and beta-glucans. In cosmetics, it appears in moisturizers, creams, and protective balms within natural formulations. It works by creating a lightweight film on the skin's surface, which helps shield against dehydration and external stressors like wind or pollutants, while allowing skin to breathe. This barrier function supports the skin's natural defenses without clogging pores.
