Abstract

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.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 224 words
A method for reducing facial wrinkles comprising: 1. tightly applying to wrinkle prone areas of the human face a pressure-sensitive adhesive appliance in such a manner that the skin under the appliance is placed in a flattened and smoothed configuration; 2. allowing the appliance to remain in place for at least four hours; 3. removing the appliance and thereby strip therewith dead skin cells from the surface of the skin; and 4. repeating steps 1, 2 and 3 a plurality of times with no more than 48 hours elapsing between a repetition thereof and said repetition being continued for at least 15 days; and wherein the said appliance is capable of transmitting an amount of moisture at least equal to the moisture transmitted by the normal facial skin of a human at rest and wherein the appliance is comprised of a film and a pressure-sensitive adhesive coating thereon, said film having a tensile strength of at least 3 pounds per inch, and an ultimate elongation of between 20 and 150%, said pressure-sensitive adhesive providing an adhesion of between 5 and 50 ounces per inch between the adhesive and the film and between 2 and 30 ounces per inch between the adhesive and the skin and the adhesion between the adhesive and the film is greater than the adhesion between the adhesive and the skin.
Claim 2
Independent Claim 224 words
A method for reducing facial wrinkles comprising: 1. tightly applying to wrinkle prone areas of the human face a pressure-sensitive adhesive appliance in such a manner that the skin under the appliance is placed in a flattened and smoothed configuration; 2. allowing the appliance to remain in place for at least four hours; 3. removing the appliance and thereby strip therewith dead skin cells from the surface of the skin; and 4. repeating steps 1, 2 and 3 a plurality of times with no more than 48 hours elapsing between a repetition thereof and said repetition being continued for at least 15 days; and wherein the said appliance is capable of transmitting an amount of moisture at least equal to the moisture transmitted by the normal facial skin of a human at rest and wherein the appliance is comprised of a film and a pressure-sensitive adhesive coating thereon, said film having a tensile strength of at least 3 pounds per inch, and an ultimate elongation of between 20 and 150%, said pressure-sensitive adhesive providing an adhesion of between 5 and 50 ounces per inch between the adhesive and the film and between 2 and 30 ounces per inch between the adhesive and the skin and the adhesion between the adhesive and the film is greater than the adhesion between the adhesive and the skin.
Claim 3
Dependent Claim 16 words
The method of claim 1 wherein the appliance remains in place for at least 6 hours.
Claim 4
Dependent Claim 22 words
The method of claim 1 wherein steps 1, 2 and 3 are repeated with no more than 36 hours between a repetition.
Claim 5
Dependent Claim 21 words
The method of claim 1 wherein the repetition of steps 1, 2 and 3 is continued for at least 30 days.
Claim 6
Dependent Claim 21 words
The method of claim 1 wherein the repetition of steps 1, 2 and 3 is continued for at least 60 days.
Claim 7
Dependent Claim 17 words
The method of claim 1 wherein the ultimate elongation of the film is between 40 and 100%.
Claim 8
Dependent Claim 14 words
The method of claim 1 wherein the film and /or the adhesive is hypoallergenic.
Claim 9
Dependent Claim 16 words
The method of claim 1 wherein the film and/or adhesive is a high polymer or copolymer.
Claim 10
Dependent Claim 29 words
The method of claim 1 wherein the thickness of the film is between 4 and 10 mils and the thickness of the adhesive is between 11/2 and 4 mils.
Claim 11
Dependent Claim 19 words
