The invention discloses a moisturizing face cream containing exopolysaccharides of tremella fuciformis spores. A preparation process of the exopolysaccharides of the tremella fuciformis spores includes the following steps: taking a liquid supernatant of a fermentation broth of the tremella fuciformis spores, and adding absolute ethyl alcohol for performing precipitation; and then adding water to the precipitation for dissolution, then taking the liquid supernatant and removing a protein by utilizing a Sevage method, obtaining the liquid supernatant by centrifugation, then adding ethanol for performing the precipitation, and subjecting the precipitation to freeze drying to obtain the exopolysaccharides of the tremella fuciformis spores. The moisturizing face cream utilizes the fermentationbroth of the tremella fuciformis spores as a raw material, and separates and extracts the exopolysaccharides having a moisturizing effect, purified exopolysaccharides have a good moisturizing effect,and even the moisturizing
