  • Patent number: 3949741
    Abstract: A method and appliance for reducing facial wrinkles. In the method, a pressure-sensitive adhesive appliance is tightly applying to wrinkle prone areas of the human face in such a manner that the skin under the appliance is placed in a flattened and smoothed configuration. The appliance remains in place for at least four hours and then is removed in a manner to strip dead skin cells from the skin. These steps are repeated a plurality of times over a long period of time.The appliance transmits moisture at least equal to that transmitted by facial skin of a human and is comprised of a film and a pressure-sensitive adhesive coating. The film has a tensile strength and an ultimate elongation consistent with flattening and smoothening the skin. The adhesion between the adhesive and the film is greater than the adhesion between the adhesive and the skin.
