What it is
Tremella fuciformis extract is obtained from the edible white jelly (snow) mushroom and is rich in water-binding polysaccharides. In cosmetics it acts as a humectant that helps draw and hold moisture and can give a soft, smooth feel, sometimes also contributing light viscosity to the water phase. In sunscreens it is included to improve hydration and sensory feel rather than for any UV role.
Safety & warnings
As a polysaccharide-rich botanical extract, Tremella fuciformis extract is generally considered mild and well tolerated. As with any botanical, sensitivity is possible in predisposed individuals. It is not a recognized fragrance allergen.
Origin & sourcing
Natural, derived from the fruiting body of the snow mushroom Tremella fuciformis, typically by aqueous extraction.
