A method for producing a bake type cosmetic composition, the method comprising the steps of:
- (a) mixing a water-soluble gelling agent-containing aqueous phase part, an emulsifier, an oil phase part, and a powered part;
- (b) loading the mixture into a mold and cooling the mixture;
- and
- (c) releasing the molded body from the mold and lyophilizing same after step (b),
- wherein the cooling in step (b) is carried out at a temperature of −60 to −30° C.,
- wherein the lyophilizing in step (c) is carried out at a temperature of −60 to −30° C., under a pressure condition of 50 to 200 pa,
- wherein the bake type cosmetic composition includes 30 to 60% by weight of an aqueous phase part, 1 to 5% by weight of an oil phase part, 0.1 to 3% by weight of an emulsifier, and 20 to 60% by weight of a powder part, based on the total weight of the composition,
- wherein the water-soluble gelling agent is contained in an amount of 0.001-10% by weight, based on the total weight of the composition.
