Snow Mushroom (Tremella Fuciformis)
A natural humectant that holds up to 500x its weight in water. Smaller molecular size than HA means potentially better penetration, though head-to-head data is limited.
Skin types
dry, normal, combination, sensitive, oily
Natural source
Extracted from Tremella fuciformis, an edible jelly mushroom used in traditional Chinese medicine. Its polysaccharides form a flexible, moisture-retaining film on the skin.
