Abstract: 1. A cosmetic product for removing keratotic skin plugs comprising: (i) a flexible non-occlusive substrate sheet; and (ii) a composition containing a poly(methyl vinyl ether/maleic anhydride) copolymer in an amount from 50 to 100% by weight of the composition deposited onto the substrate sheet, the composition being dry non-tacky to the touch after deposition and upon being wetted for use the composition turns tacky and mobile. 2. The product according to claim 1 wherein the substrate is a breathable fabric. 3. The product according to claims 1 or 2 wherein the fabric is selected from the group consisting of rayon, polyester, polypropylene and mixtures thereof. 4. The product according to any preceding claim wherein the deposited polymer and substrate are present in a weight ratio ranging from 0.1:1 to 1,000:1. 5. The product according to any preceding claim wherein the polymer is water-soluble. 6. The product according to any preceding claim wherein mobility of the composition is characterized by a yield point ranging from 1 to 400 Pascals. 7. A cosmetic method for removing keratotic plugs from skin pores comprising: (a) wetting an area of skin to be treated with a wetting agent comprising a fluid; (b) applying a plug removing product onto the area, the product comprising: (i) a flexible non-occlusive substrate sheet; and (ii) a composition containing a poly(methyl vinyl ether/maleic anhydride) copolymer in an amount from 50 to 100% by weight of the composition deposited onto the substrate sheet, the composition being dry non-tacky to the touch after deposition and upon being wetted for use the composition turns tacky and mobile; (c) allowing the fluid to tackify the composition and then to evaporate from, the area covered by the product thereby causing the composition to dry in contact with the skin; and (d) peeling away the product from the skin thereby removing keratotic plugs now adhesively attached to the composition. 8. The method according to claim 7 wherein the fluid is selected from the group consisting of water, alcohol and mixtures thereof. 9. A cosmetic method for removing keratotic plugs from skin pores through use of a cosmetic product, the product comprising: (i) a flexible non-occlusive substrate sheet; and  (ii) a composition containing a poly(methyl vinyl ether/maleic anhydride) copolymer in an amount from 50 to 100% by weight of the composition <DP=3deposited onto the substrate sheet, the composition being dry non-tacky to the touch after deposition and upon being wetted for use the composition turns tacky and mobile; the method comprising: (a) placing a wetting agent comprising a fluid onto a surface of the cosmetic product whereon the composition is deposited thereby turning the composition into a tacky and mobile material; (b) applying the wetted cosmetic product onto an area of skin to be treated; (c) allowing fluid to evaporate from the area covered by the product; and (d) peeling away the product from the skin thereby removing keratotic plugs now adhesively attached to the composition. 10. The method according to claim 9 wherein the fluid is selected from the group consisting of water, alcohol and mixtures thereof.
