It is intended to provide a technique which aims at conveniently and highly accurately selecting a cosmetic suitable for each user and a technique for designing such a cosmetic. More specifically speaking, it is intended to provide a novel indication for evaluating the suitability of a makeup cosmetic for the skin and a method of fully utilizing this indication. By using the difference between the surface free energy of a cosmetic and the surface free energy of the skin as an indication, the suitability level of a specific cosmetic for the skin is evaluated. Then, the composition of the cosmetic is determined so as to minimize the difference between the surface free energy of a cosmetic and the surface free energy of the skin.
