Our take
Is Tremella Fuciformis Polysaccharide a Good Ingredient?
It rates Good for reliable humectant and film-forming hydration with a light, comfortable feel, though solid clinical data are more limited than for hyaluronic acid. The benefits are mainly moisturization rather than targeted treatment, which keeps it a notch below Great.
