Self-adhesive skin patch and combination set for cosmetic skin care

Abstract

The present invention relates to a skin patch comprising a matrix adhering to the skin and containing at least one active cosmetic substance and a combination with a skin wrapping to generate an effective compression for the treatment of cellulite and/or striae.

1 . A skin patch, wherein the skin patch comprises a matrix which is capable of adhering to human skin and comprises at least one polymer and one or more active cosmetic substances which comprise carnitine, and wherein the skin patch is capable of exerting a pressure on skin, which pressure is up to 10 mm Hg. 
     
     
         2 . The skin patch of  claim 1 , wherein the pressure is at least 4 mm Hg. 
     
     
         3 . The skin patch of  claim 1 , wherein the at least one polymer gels in water. 
     
     
         4 . The skin patch of  claim 3 , wherein the at least one polymer comprises a polymer of at least one of acrylic acid and a salt thereof. 
     
     
         5 . The skin patch of  claim 4 , wherein the at least one polymer comprises a polymer of sodium acrylate and acrylic acid. 
     
     
         6 . The skin patch of  claim 1 , wherein the skin patch comprises from 0.01% to 10% by weight of carnitine, based on a total weight of the matrix. 
     
     
         7 . The skin patch of  claim 6 , wherein the skin patch comprises from 0.1% to 1% by weight of carnitine. 
     
     
         8 . The skin patch of  claim 1 , wherein the skin patch comprises at least one further active cosmetic substance. 
     
     
         9 . The skin patch of  claim 8 , wherein the at least one further active cosmetic substance comprises white tea extract. 
     
     
         10 . The skin patch of  claim 1 , wherein the skin patch further comprises caffeine. 
     
     
         11 . The skin patch of  claim 1 , wherein the skin patch further comprises capsaicin. 
     
     
         12 . The skin patch of  claim 4 , wherein the matrix comprises from 2% to 55% by weight of the polymer of at least one of acrylic acid and a salt thereof. 
     
     
         13 . The skin patch of  claim 5 , wherein the matrix comprises from 5% to 30% by weight of the polymer of sodium acrylate and acrylic acid. 
     
     
         14 . The skin patch of  claim 1 , wherein the skin patch comprises a polymer of sodium acrylate and acrylic acid, carnitine, water, sodium carboxymethylcellulose, dihydroxyaluminum aminoacetate, hydroxypropylcellulose, glycerol, disodium edetate, kaolin, methyl para-hydroxybenzoate, propylene glycol and castor oil. 
     
     
         15 . The skin patch of  claim 1 , wherein the matrix exhibits an adhesion time value of higher than 5. 
     
     
         16 . A skin patch, wherein the skin patch comprises a matrix which is capable of adhering to human skin and comprises at least one polymer and one or more active cosmetic substances, the one or more active substances comprising from 0.1% to 1% by weight of carnitine, based on a total weight of the matrix, and the at least one polymer comprising a polymer of at least one of acrylic acid and a salt thereof, and wherein the skin patch is capable of exerting a pressure on skin, which pressure is from 4 mm Hg to 7 mm Hg. 
     
     
         17 . The skin patch of  claim 16 , wherein the at least one polymer comprises a polymer of sodium acrylate and acrylic acid. 
     
     
         18 . The skin patch of  claim 17 , wherein the matrix comprises from 5% to 30% by weight of the polymer of sodium acrylate and acrylic acid. 
     
     
         19 . The skin patch of  claim 17 , wherein the patch exhibits an adhesion time value of higher than 5. 
     
     
         20 . A kit comprising the skin patch of  claim 1  and a gas and vapor permeable skin wrapping.
