Tremella fuciformis polysaccharide is it can be used as an emulsion stabilizer, film former, or skin conditioner and is apparently able to help the skin retain moisture. It is also credited with skin-protecting, anti-inflammatory, and anti-allergenic properties. There is some clinical evidence that it may help increase superoxide dismutase activity and thus be effective in anti-aging formulations. This is the polysaccharide fraction derived from the tremellia fuciformis mushroom. Its primary constituent is glucoronoxylomannan.
