What Is Phellinus Linteus Mycelium Extract?
Phellinus Linteus Mycelium Extract comes from the thread-like network, or mycelium, of the mushroom species Phellinus linteus. While the fruiting body of this mushroom has been studied in traditional wellness circles, the cosmetic world focuses on the mycelium because it is rich in polysaccharides, amino acids and skin-loving sugars that help seal in moisture. Interest in Asian beauty labs during the early 2000s sparked its rise in skincare after formulators noticed its soothing feel and natural conditioning effect.
The extract is usually made by cultivating the mushroom on a sterile plant-based medium. Once the mycelium matures, it is harvested, dried and ground. A gentle water or glycerin-based extraction pulls out the beneficial components which are then filtered and concentrated into a stable liquid or powder for use in cosmetics.
You will most often spot Phellinus Linteus Mycelium Extract in moisturizers, hydrating serums, sheet masks, calming lotions and after-sun gels where a soft skin finish is desired.

Comedogenic Rating
Comedogenic rating: 1 out of 5. Phellinus Linteus Mycelium Extract is largely water-soluble and composed of lightweight polysaccharides rather than heavy oils or waxes, so it is unlikely to clog pores. Its main role is to condition the skin surface without leaving an occlusive residue, which keeps the risk of blackheads or pimples very low. Therefore it is generally suitable for acne-prone or breakout-prone skin. As with any ingredient, the overall formula and presence of other, more pore-blocking components can influence the final comedogenicity, so check the full ingredient list of the product you plan to use.
Summary
Phellinus Linteus Mycelium Extract works as an emollient that smooths, softens and lightly shields the skin against water loss, thanks to its natural mix of polysaccharides and amino acids. While not a mainstream hero ingredient, it enjoys quiet popularity in East Asian skincare and is appearing more often in hydrating serums, creams and soothing masks worldwide. Topical use is considered safe for most people with only rare reports of mild irritation or allergy. As with any new cosmetic ingredient it is wise to perform a quick patch test first to confirm personal compatibility.
