What Is Hypsizygus Ulmarius Mycelium Extract?
Hypsizygus Ulmarius Mycelium Extract comes from the mycelium, the root-like network, of the elm oyster mushroom Hypsizygus ulmarius. This mushroom has long been valued in East Asian cuisine and folk remedies, but its skincare appeal is more recent. Scientists found that the mycelium is rich in beta-glucans, amino acids, minerals and protective antioxidants that help support the skin’s barrier and moisture levels.
The extract is produced through a sterile fermentation process. The mushroom is grown on nutrient media, the mycelium is harvested then subjected to water or gentle solvent extraction to pull out the bioactive compounds. The liquid is filtered, concentrated and finally dried or preserved in solution, creating a stable ingredient that can be blended into cosmetic bases.
You will usually spot Hypsizygus Ulmarius Mycelium Extract in hydrating sheet masks, calming serums, barrier-repair moisturizers, after-sun gels and anti-aging creams that focus on strengthening and soothing the skin.
