Abstract:
The present invention provides a cosmetic shaped product: which is substantially formed with relatively low-molecular-weight hyaluronic acid or a water-soluble salt thereof having a high penetrability into the skin; which is easily soluble to water; and which has satisfactory handling properties, and a method for producing the cosmetic shaped product. There is provided a cosmetic shaped product being a sponge-like shaped body formed with at least one polyanionic polysaccharide of hyaluronic acid and a water-soluble salt thereof each having an average molecular weight of 30,000 or lower, the sponge-like shaped body having a bulk specific gravity of 5 to 500 mg/mL. This cosmetic shaped product can be produced by freeze-drying an aqueous solution having a content of the polyanionic polysaccharide of 0.5 to 30% by mass.
