Tremella, also known as snow mushroom or silver ear mushroom, is a gelatinous fungus used in skincare as an extract, prized for its exceptional hydrating, antioxidant, and skin-plumping properties, driven by its high polysaccharide content.

Tremella fuciformis, commonly called snow mushroom, is a jelly-like edible fungus native to subtropical and tropical regions, including China, Japan, and Southeast Asia, often growing on decaying wood. In skincare, it’s used as an extract, obtained by drying and processing the mushroom’s fruiting body with water or solvent extraction, concentrating its bioactive polysaccharides (up to 70–90% of its dry weight), along with small amounts of proteins, vitamins (like D), and minerals. Known in Traditional Chinese Medicine for centuries as a beauty and longevity tonic, tremella appears in serums, moisturizers, masks, and essences, listed as "Tremella fuciformis extract," "snow mushroom extract," or "Tremella polysaccharide." Its ability to hold up to 500 times its weight in water rivals hyaluronic acid, making it a star in hydration-focused products, especially in Asian beauty trends like K-beauty. The extract has a lightweight, gel-like texture with a neutral scent, blending seamlessly into formulations to enhance moisture and radiance.

Tremella offers several skincare benefits:

Intense Hydration: Polysaccharides draw and retain moisture, plumping skin and reducing dryness, providing a lightweight alternative to heavier humectants.
Antioxidant Protection: Neutralizes free radicals, protecting skin from oxidative stress and environmental damage, helping to prevent fine lines and dullness.
Skin Plumping: Enhances skin elasticity and firmness by locking in hydration, smoothing texture and giving a dewy, youthful glow.
Soothing: Its gentle, anti-inflammatory properties calm irritation and sensitivity, benefiting reactive or stressed skin without clogging pores.
Brightening: Improves water retention and circulation, promoting a radiant, even complexion over time, especially for tired or dehydrated skin.
Note: Tremella is highly biocompatible and safe for most skin types, with a low risk of irritation. Allergic reactions are rare, though those sensitive to mushrooms should patch-test. It’s non-comedogenic and pairs well with other hydrators.
