PROBLEM TO BE SOLVED: To provide a liquid foundation product containing hyaluronic acid as a moisturizing component, in which the skin does not dry after use and has no sticky feeling. SOLUTION: A moisturizing composition containing hyaluronan crosspolymer Na, sodium hyaluronate, acetylated sodium hyaluronate, and hydrolyzed sodium hyaluronate. Such a moisturizing composition has a 4D three-dimensional sponge layer structure constructed by combining four kinds of sodium hyaluronate having different properties in combination to efficiently store and retain water, and to form the surface of the skin, stratum corneum, and epidermis. By squeezing into the dermis and exhibiting multiple moisturizing effects instantaneously, that is, by supplying water to the outside of the skin and retaining water inside, skin care can be performed on a level-by-level basis. Further, the deep moisturizing liquid foundation containing the moisturizing composition has a deep moisturizing effect and is refreshing and non-sticky. [Selection diagram] Figure 1
