The present invention provides a cosmetic for skin containing a water-soluble polymer having a cyclic structure in a main chain or a side chain, and a water-soluble polymer having a dimethyl or trimethyl amino group, and a method for evaluating the elasticity of the cosmetic. The evaluation method of the elastic feeling of the cosmetic includes: measuring the area of the undried film, namely the first area, and the area of the dry film, namely the second area, And calculate the ratio of the second area to the first area, the area of the undried film, that is, the first area and the area of the dry film, that is, the second area. Cosmetic formation of water-soluble polymers and coloring substances. |
