PURPOSE: To provide a method for slush molding a two-layer skin in the case of integral foaming in which a second layer having substantially equal physical properties to those of a first layer can be formed uniformly on the first layer and a material cost can be deleted.

CONSTITUTION: The method for slush molding a two-layer skin comprises the steps of adhering a material for a first layer 2 such as powderlike vinyl chloride, etc., in a laminar state in a heated slush mold, then adhering a material for a second layer 3 thereon to form a skin 1 of an integrated two-layer structure, wherein a high purity material is used as the material for the layer 2, and regenerated vinyl chloride powder is used are the material for the layer 3.
