▎ 摘　　要

NOVELTY - Heterofacial differential function bidirectional attached hydrogel facial mask, comprises a first hydrogel functional layer, a second hydrogel functional layer and an isolation layer. The first hydrogel is coated on one side of the isolating layer to prepare the first hydrogel functional layer. The second hydrogel is coated on the other side of the isolation layer to prepare the second hydrogel functional layer. USE - The heterofacial differential function bidirectional attached hydrogel facial mask is useful for cleaning, adsorption, moisturizing and nourishing and repairing of skin (claimed). ADVANTAGE - The heterofacial differential function bidirectional attached hydrogel facial mask: has two differentiated skin care effects; and forms a two-way adhesion hydrogel mask with differentiated functions on different surfaces. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing heterofacial differential function bidirectional attached hydrogel facial mask comprising (1) preparing the first hydrogel, (a) placing polyvinyl alcohol, polyvinylpyrrolidone, chitosan, and glycerol in deionized water, heating and stirring until completely dissolved, adding graphene oxide and stir until uniformly mixed, cooling down, and obtaining a ready-to-use mixture A, (b) placing the kaolin in deionized water, stirring and swelling at room temperature, adding to the above-mentioned mixture A, and stirring until it is evenly mixing to obtain the first hydrogel, and (2) (a) placing polyvinyl alcohol, polyvinylpyrrolidone, and glycerol in deionized water, heating and stirring until they are completely dissolved, and cooling down to obtain a ready-to-use mixture B, (b) placing sodium alginate in deionized water, stirring at room temperature, adding to the above-mentioned ready-to-use mixture B, stirring until it is evenly mixed, adding sodium hyaluronate, 1,2-hexanediol, oligo peptide-1, acetyl hexapeptide-8, tripeptide-1 copper, Aloe extract, ginseng extract, stirring until uniformly mixed to obtain the second hydrogel, and (3) applying the first hydrogel and the second hydrogel to both sides of the waterproof membrane in turn to obtain a two-way adhesion hydrogel mask with the first hydrogel functional layer and the second hydrogel functional layer. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of preparation process of a heterofacial differential function bidirectional attached hydrogel facial mask (Drawing includes non-English language text).
