Abstract: The purpose of the present invention is to provide a two-component cosmetic which, when a first formulation and a second formulation are sequentially applied, forms a uniform gel film on the skin while imparting a feeling of moisture permeating the skin, thereby providing an ideal skin feel. The present invention pertains to a two-component cosmetic containing: (1) a first formulation containing a gel formation-promoting substance; and (2) a second formulation containing a gel-forming substance. The two-component cosmetic is characterized in that the first formulation is applied to the skin, and then the second formulation is applied thereto.
