Kind Code:
A1
Abstract:
Disclosed are a hyaluronic acid facial mask, a preparation method therefor and a use method therefor. The facial mask comprises 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 electrostatic spinning method. The hyaluronic acid composite comprises a dispersed phase and a solvent phase. The dispersed phase comprises, in terms of mass percentage content, 70-95% of hyaluronic acid. The solvent phase comprises water. The preparation method comprises: spinning the hyaluronic acid composite on the substrate layer using an electrostatic spinning method to form a hyaluronic acid layer, and then attaching the protective paper layer on the hyaluronic acid layer. During use, water is applied to a part to be used, and then the hyaluronic acid layer of a facial mask from which the protective paper layer has been removed is directly attached to the part to be used. The facial mask is easy to prepare, reduces the usage of hyaluronic acid, and improves the utilization rate of hyaluronic acid.
