Abstract: Disclosed in this specification is a composition comprising polymer hyaluronic acid nanoparticles. In the present disclosure, the polymer hyaluronic acid is micronized to facilitate skin penetration without depolymerization of the polymer hyaluronic acid, and may be stably comprised in a formulation. In addition, the micronized polymer hyaluronic acid comprised in the composition of the present disclosure penetrates the skin and then is neutralized to pH of the skin and expanded in size again, which can provide excellent benefits for moisturizing the skin and improving skin elasticity.

Abstract: Disclosed in the present specification is a technology for quantifying properties of a cosmetic film formulation using a cosmetic film applied on a polymeric substrate having physical properties similar to skin, and for quantifying the degree of deformation due to application of a cosmetic composition using a non-destructive analysis technique through X-ray CT, thereby objectively quantifying the degree of pulling of the cosmetic film using this technology.
