Abstract
A cosmetic product is provided for removing keratotic skin plugs. The product includes a flexible non-occlusive substrate sheet onto which a composition containing an anionic or nonionic polymer is deposited. The composition is treated to become dry non-tacky to the touch yet upon being wetted for use the composition again turns tacky and mobile. The method of application involves either directly moistening the product or indirectly moistening by first wetting a consumer's face in an area where the product is applied. Thereafter, water is allowed to evaporate leaving a film to which the keratotic plugs are bonded. The film is then peeled away concommittingly removing the plugs.
