The invention provides a moistening mask liquid without an emulsifier. The moistening mask liquid comprises, by weight, 5 to 12% of a humectant, 0.5 to 3.0% of a suspension stabilizing agent, 1 to 10% of grease, 1.0 to 5.0% of a water-soluble active substance, 0.5 to 5.0% of a fat-soluble active substance, 1.0 to 10% of plant extract and 0.01 to 0.3% of a pH value conditioning agent, with the balance being deionized water, wherein the grease is one or more selected from the group consisting of sunflower oil, jojoba oil, avocado oil, olive oil, aloe oil and sweet almond oil, and the suspension stabilizing agent is a three-dimensional stabilizing agent prepared by coating a microcrystalline cellulose porous particle with a particle size of 0.1 to 20 [mu]m with xanthan gum or carboxymethylcellulose sodium. The mask liquid provided by the invention employs the microcrystalline cellulose porous particle in the suspension stabilizing agent to absorb grease with the dissolved fat-soluble active substance and uses xanthan gum or carboxymethylcellulose sodium for suspension adsorption of the porous particle with grease, so the stable mask liquid without any emulsifier is formed; and the mask liquid has no irritation to the skin, and supplements water to the skin and moistens the skin when used, and microcrystalline cellulose particles in a specific particle size range can provide the skin with slippery sensation.
