For nearly a thousand years, court physicians in imperial China prescribed a single ingredient to preserve the complexion of Empress Yang Guifei — a delicate, jelly-like fungus that bloomed on fallen wood after rain. They called it the silver ear. Today, science calls it Tremella fuciformis — the snow mushroom — and it is quietly displacing hyaluronic acid as the most sophisticated hydrator in modern skincare.
For two decades, hyaluronic acid has held the title of gold-standard humectant — the molecule every serum, mist and moisturiser is benchmarked against. But peer-reviewed research now suggests that snow mushroom does not simply rival hyaluronic acid. In several measurable respects, it surpasses it.
Here is what the science says — and why we built our most luxurious hydration cream around it.
A single bioactive performing three measurable functions — the reason it has earned its place in modern formulation.
Snow mushroom belongs to a class of bioactives known as fungal polysaccharides — long, branching chains of sugar molecules that behave as water reservoirs at the cellular level.
What makes Tremella fuciformis genuinely different is molecular weight. The polysaccharide chain is structurally smaller than standard hyaluronic acid, which allows it to travel beyond the surface and deliver hydration into the deeper layers of the epidermis — not simply sit on top of the skin.
Tremella fuciformis is rich in phenolic compounds — naturally occurring molecules that neutralise free radicals before they degrade collagen or trigger oxidative stress.
Research documented in the International Journal of Biological Macromolecules demonstrates strong scavenging activity against the reactive oxygen species responsible for premature ageing, dullness and uneven tone.
In practical terms — it hydrates and defends in the same step.
For sensitive, reactive or compromised skin, snow mushroom does something most humectants cannot. Studies published in Phytotherapy Research confirmed its capacity to reduce visible redness, calm irritation and accelerate the recovery of minor surface damage.
This makes it one of the few high-performance hydrators that does not provoke barrier-stressed skin — it actively supports it.
Most hydrators add water to the skin. Snow mushroom teaches the skin to hold its own.
Built around Tremella fuciformis and paired with the bioactives that amplify its effect — for hydration that doesn't sit on the skin, but settles into it.
Three peer-reviewed studies underpin the claims made throughout this article.
Documents topical Tremella fuciformis polysaccharide effects on stratum corneum hydration, transepidermal water loss, and skin elasticity — supported by a flexible film-forming polysaccharide matrix that retains moisture longer than common emollients.
Characterises the phenolic compound profile of Tremella fuciformis and demonstrates its scavenging activity against the reactive oxygen species responsible for oxidative stress, photoageing and uneven skin tone.
Confirms the capacity of Tremella fuciformis extract to reduce visible redness, calm irritation, and accelerate recovery of minor surface damage on sensitive, reactive and barrier-compromised skin.
All claims verified against original peer-reviewed publications.
