  • Patent number: 5026552
    Abstract: The material according to the invention comprises a mesh (3) confining a hydratable gel (4) in a thin film is its holes. The gel is used for its properties of absorption of the water provided by a moistening of the surface of the skin; it is rehydrated at least partially and with the mesh resuming its natural flexibility molds to the irregularities of the body; then it dries under the influence of the normal skin temperature, the dry form being resumed while it continues to adhere to the skin. Because the gel is confined in its mesh, it can be pulled off all in one piece, so that the gel thereby performs a skin sloughing treatment.
