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.
