Skin-attachable patch and method for using skin-attachable patch
Proposed are a patch for attachment on the skin and a method of using the patch for attachment on the skin. The patch includes a base sheet and a film which is disposed on the base sheet and of which thickness is decreased by an activating material.
1 . A patch for attachment on the skin, comprising:
a base sheet; and
a film disposed on the base sheet,
wherein the film includes:
a first layer adjacent to the base sheet, the first layer configured such that, in response to application of an activating material to the film, at least a portion of the first layer is melted, thereby decreasing a thickness of the first layer, and
a second layer arranged on one side of the first layer and including an effective material configured to be delivered to the skin,
wherein a transparency of the film increases as the thickness of the first layer decreases.
2 . The patch of claim 1 , wherein the activating material is configured to be sprayed on the film.
3 . The patch of claim 1 , wherein in response to application of the activating material to the film, the film becomes softer.
4 . The patch of claim 1 , further comprising:
an interlayer arranged between the first layer and the base sheet, wherein the interlayer has a smaller adhesive force than the second layer.
5 . The patch of claim 4 , wherein the interlayer is configured such that, in response to contact with a solution, an adhesive force of the interlayer is decreased.
6 . A method of using the patch of claim 1 for attachment to skin, the method comprising:
attaching the film to the skin; and
applying an activating material to the film to decrease a thickness of the film.
