Abstract
Abstract A method for the cosmetic treatment of human skin, particularly facial skin, for the removal of materials from the surface and the sebaceous follicles is disclosed. The method comprises applying a layer of liquid polymerizable adhesive to the skin, then applying a pliable adhesive tape to cover the applied liquid adhesive and allowing the polymerization of said layer of polymerizable adhesive to take place and then removing the layer of polymerized adhesive from the skin by stripping the tape from the skin. In this treatment the materials on the surface of the skin and within the sebaceous follicles being attached to and removed with the layer of polymerized adhesive along with the tape. Alpha-cyanoacrylate is usefully employed as the polymerizable adhesive in this treatment.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
89 words
A method for the cosmetic treatment of facial skin and the like for the removal of materials from the surface and the sebaceous follicles of human skin which comprises applying a coating or film of liquid polymerizable cyanoacrylate adhesive to said ski, allowing the polymerization of said coating of polymerizable adhesive, and removing the coating of polymerized adhesive from the skin when adhesive is fully polymerized, the materials from the surface of the skin and the sebaceous follicles being attached to and removed with the layer of polymerized adhesive.
Claim 2
Independent Claim
89 words
A method for the cosmetic treatment of facial skin and the like for the removal of materials from the surface and the sebaceous follicles of human skin which comprises applying a coating or film of liquid polymerizable cyanoacrylate adhesive to said ski, allowing the polymerization of said coating of polymerizable adhesive, and removing the coating of polymerized adhesive from the skin when adhesive is fully polymerized, the materials from the surface of the skin and the sebaceous follicles being attached to and removed with the layer of polymerized adhesive.
Claim 3
Dependent Claim
15 words
A method of claim 1, wherein the materials include bacteria, fungi, mites, and follicular horn.
Claim 4
Dependent Claim
15 words
A method of claim 1 wherein said coating of polymerizable adhesive comprises alpha methyl cyanoacrylate.
Claim 5
Dependent Claim
23 words
A method of claim 1, wherein said coating of polymerizable adhesive is applied at a substantially uniform thickness on the skin by brushing.
Claim 6
Dependent Claim
39 words
A method of claim 1, wherein said coating of polymerized adhesive is removed by contacting the layer with a second adhesive on a pliable backing or tape and lifting or peeling away said backing or tape from the skin.
Claim 7
Dependent Claim
12 words
A method of claim 5, wherein the backing or tape is cloth.
Claim 8
Dependent Claim
12 words
A method of claim 5, wherein the backing or tape is paper.
Claim 9
Dependent Claim
15 words
A method of claim 5, wherein the backing or tape is plastic such as polyester.
Claim 10
Dependent Claim
80 words
A cosmetic method for the removal of surface material from the skin and from the sebaceous follicles of the skin which comprises applying a thin, substantially uniform coating or film of a liquid polymerizable cyanoacrylate adhesive to the skin, contacting the cyanoacrylate layer with an adhesive tape, said tape adhering to said cyanoacrylate coating, and removing the polymerized cyanoacrylate coating or film from the skin when substantially fully polymerized by lifting or peeling away said tape away from the skin.
Claim 11
Dependent Claim
80 words
A cosmetic method for the removal of surface material from the skin and from the sebaceous follicles of the skin which comprises applying a thin, substantially uniform coating or film of a liquid polymerizable cyanoacrylate adhesive to the skin, contacting the cyanoacrylate layer with an adhesive tape, said tape adhering to said cyanoacrylate coating, and removing the polymerized cyanoacrylate coating or film from the skin when substantially fully polymerized by lifting or peeling away said tape away from the skin.
Claim 12
Dependent Claim
15 words
A method of claim 9, wherein the materials include bacteria, fungi, mites and follicular horn.
Claim 13
Dependent Claim
12 words
A method of claim 9, wherein the cyanoacrylate is alpha methyl cyanoacrylate.
Claim 14
Dependent Claim
12 words
A method of claim 9, wherein the tape is a plastic tape.
Claim 15
Dependent Claim
12 words
A method of claim 9, wherein the tape is a cloth tape.
Claim 16
Dependent Claim
12 words
A method of claim 9, wherein the tape is a paper tape.
Claim 17
Dependent Claim
30 words
A method of claim 9, wherein said coating or film of polymerizable adhesive is applied in an amount sufficient to uniformly wet and coat the skin surface to be treated.
Claim 18
Dependent Claim
26 words
A method according to claim 9, wherein another coating of polymerizable adhesive is applied to the coating of cyanoacrylate adhesive before contact with said adhesive tape.
Claim 19
Dependent Claim
27 words
A method according to claim 16, wherein said other coating of polymerizable adhesive is applied before polymerization of the first applied coating of liquid polymerizable cyanoacrylate adhesive.
Claim 20
Dependent Claim
27 words
A method according to claim 16, wherein said other coating of polymerizable adhesive is applied after polymerization of the first applied coating of liquid polymerizable cyanoacrylate adhesive.
Claim 21
Dependent Claim
25 words
A method according to claim 16, wherein said adhesive tape is applied to said other coating of polymerizable adhesive before said other coating has polymerized.
Claim 22
Dependent Claim
