Tremella Fuciformis Sporocarp Extract
Tremella Fuciformis Sporocarp Extract is a polysaccharide derived from the edible fruit bodies (sporocarp) of the Silver Ear mushroom (Tremella fuciformis), native to China. It is a large molecule (over 1 million Da molecular weight) composed of sugar constituents including Mannose, Xylose, and Glucuronic acid. Glucuronic acid is also a major component of hyaluronic acid, which underpins the extract's moisturizing properties. According to CosIng, its official functions include antioxidant, hair conditioning, humectant, and skin conditioning.
Tremella extract is claimed to have slightly greater water-holding capacity than hyaluronic acid, making it a potent moisturizer. It also exhibits antioxidant activity and is noted for leaving skin moist and smooth without the stickiness typical of many humectants.
