Specifically, first, a freeze-dried collagen powder is dispersed in a solvent to prepare a polymer solution. The temperature and humidity during the preparation of the polymer solution are normal temperature. Next, the polymer solution thus prepared is supplied to a nozzle in an electrospinning apparatus and electrospun on one surface side of the base material layer 10 to be crosslinked. As a result, the collagen-containing nanofiber layer 20 is formed. Thus, a laminate in which the base material layer 10 and the collagen-containing nanofiber layer 20 are laminated is formed.

  As the collagen, animal-derived collagen obtained from animal dermis, bone, tail, (fish) scale, etc. can be used, and plant-derived collagen such as acacia can also be used. In Embodiment 1, acacia-derived collagen is used.

  As a solvent used for the polymer solution, for example, hexafluoro-2-propanol, a solution obtained by mixing phosphate buffered saline (PBS) and ethanol at 1: 1, or the like can be used. You may mix and use another kind of solvent. The polymer solution may contain an additive such as a conductivity improver. In Embodiment 1, hexafluoro-2-propanol is used.

  To use the face mask 1 according to the first embodiment, first, as shown in FIG. 3A, the collagen-containing nanofiber layer 20 in the face mask 1 is attached to the user's face so as to contact the skin. .

  Next, as shown in FIG. 3B, the cosmetic liquid M is sprayed from the upper side of the base material layer 10 with the spray SP. As the cosmetic liquid, a cosmetic liquid for removing square plugs is used. The injected cosmetic liquid M soaks into the skin S through the base material layer 10 and the collagen-containing nanofiber layer 20. At this time, when the cosmetic liquid M passes through the collagen-containing nanofiber layer 20, the collagen C of the collagen-containing nanofibers is partially melted by the moisture of the cosmetic liquid M, and the collagen C also soaks into the skin. In this way, the dirt D is released from the surface of the skin S by the action of the cosmetic liquid M soaking into the skin. The dirt D released from the skin S moves to the collagen-containing nanofiber layer 20.

  Next, after a predetermined time has elapsed, the face mask 1 is pulled away from the skin S as shown in FIG. At this time, the dirt D absorbed by the collagen-containing nanofiber layer 20 is also removed.

  As a cosmetic liquid for removing horn plugs, cationic, anionic and amphoteric salt-forming groups, more specifically carboxyl groups, sulfonic acid group residues, sulfuric acid residues, phosphoric acid residues, nitric acid residues, It is preferable to use a polymer compound containing a salt-forming group such as an amino group or an ammonium group. In Embodiment 1, it is preferable to contain polymethacryloyloxyethyltrimethylammonium chloride.
