A hyaluronic acid facial mask, a preparation method therefor and a use method therefor is provided. The facial mask includes a substrate layer, a hyaluronic acid layer and a protective paper layer sequentially arranged. The hyaluronic acid layer is made of hyaluronic acid nanofibers. The hyaluronic acid nanofibers are formed by spinning a hyaluronic acid composite using an electrospinning method. The hyaluronic acid composite includes a dispersed phase and a solvent phase. The dispersed phase includes, in terms of mass percentage content, 70-95% of hyaluronic acid. The solvent phase includes water. The preparation method includes: spinning the hyaluronic acid composite on the substrate layer using an electrospinning method to form a hyaluronic acid layer, and then attaching the protective paper layer on the hyaluronic acid layer.
