Corrective method for fingernails or toenails
View Patent ↗The disclosure relates to a method for correcting a fingernail or toenail, comprising the application of at least one layer and the performance of at least one treatment step, wherein the at least one layer contracts or expands, as well as a fingernail or toenail that can be produced with the method.
1. A method for correcting a fingernail or toenail ( 2 ), comprising at least the following steps:
a) coating a fingernail or toenail with at least one layer ( 3 , 4 ) of at least one compound, and
b) performing of at least one treatment step, in which the at least one layer contracts or expands, wherein the degree of curvature of the fingernail or toenail ( 2 ) changes and the fingernail or toenail will thus be corrected.
2. The method according to claim 1 , whereby the at least one treatment step in step b) is a light or thermal treatment step.
3. The method according to claim 2 , whereby the at least one layer ( 3 , 4 ) is hardened during the performance of the at least one treatment step in step b).
4. The method according to claim 3 , whereby the modulus of elasticity of the at least one layer ( 3 , 4 ) lies in the range from 1 to 50 kN/mm 2 after the performance of the at least one treatment step in step b).
5. The method according to claim 2 , whereby the at least one layer ( 3 , 4 ) is hardened after the application in step a) and before the performance of the at least one treatment step in step b).
6. The method according to claim 5 , whereby the modulus of elasticity of the at least one layer ( 3 , 4 ) lies in the range from 1 to 50 kN/mm 2 after the performance of the at least one treatment step in step b).
7. The method according to claim 2 , whereby the modulus of elasticity of the at least one layer ( 3 , 4 ) lies in the range from 1 to 50 kN/mm 2 after the performance of the at least one treatment step in step b).
8. The method according to claim 2 , whereby in step a) at least one first layer ( 3 ) is applied onto the fingernail or toenail ( 2 ), and at least one second layer ( 4 ) is applied onto the at least one first layer ( 3 ), wherein the at least one first layer ( 3 ) and the at least one second layer ( 4 ) are different with regard to their chemical composition.
9. The method according to claim 8 , whereby the modulus of elasticity of the at least one layer ( 3 , 4 ) lies in the range from 1 to 50 kN/mm 2 after the performance of the at least one treatment step in step b).
10. The method according to claim 9 , whereby the at least one first layer ( 3 ) expands during the treatment step in step b).
11. The method according to claim 9 , whereby the at east one second layer ( 4 ) contracts during the treatment step in step b).
12. The method according to claim 1 , whereby the at least one layer ( 3 , 4 ) is hardened during the performance of the at least one treatment step in step b).
13. The method according to claim 1 , whereby the at least one layer ( 3 , 4 ) is hardened after the application in step a) and before the performance of the at least one treatment step in step b.
14. The method according to claim 1 , whereby the modulus of elasticity of the at least one layer ( 3 , 4 ) lies in the range from 1 to 50 kN/mm 2 after the performance of the at least one treatment step in step b).
15. The method according to claim 1 , whereby in step a) at least one first layer ( 3 ) is applied onto the fingernail or toenail ( 2 ), and at least one second layer ( 4 ) is applied onto the at least one first layer ( 3 ), wherein the at least one first layer ( 3 ) and the at least one second layer ( 4 ) are different with regard to their chemical composition.
16. The method according to claim 15 , whereby the at least one first layer ( 3 ) expands during the treatment step in step b).
17. The method according to claim 15 , whereby the at least one second layer ( 4 ) contracts during the treatment step in step b).
18. The method according to claim 1 , whereby in step a), after the application of the at least one layer ( 3 , 4 ), a protective layer is additionally applied onto the at least one layer ( 3 , 4 ).
19. The method according to claim 1 , comprising the following step in addition:
c) chemically or mechanically removing of the layer from the fingernail or toenail ( 2 ).
20. The method according to claim 1 , wherein the at least one layer ( 3 , 4 ) is substantially colorless or exhibits a color corresponding to the natural shade of the nail plate or of the nail bed.
