Skin Care Regimen Comprising At Least One Composition Comprising A Pyrithione Source

Abstract

A method of treating skin comprising: applying a first composition to a portion of skin to form a prepared surface; and contacting said prepared surface with a hair removal device to form a contacted surface, wherein said hair removal device comprises at least one of: a skin engaging member, a molded shaving aid, and a combination thereof; applying a second composition to said contacted surface to form a treated surface, wherein at least one of said first composition, said hair removal device, said second composition, or a combination thereof comprises a pyrithione source, such as zinc pyrithione.

1 ) A method of treating skin comprising:
 a) applying a first composition to a portion of skin to form a prepared surface;   b) contacting said prepared surface with a hair removal device to form a contacted surface, wherein said hair removal device comprises at least one of:
 i) a skin engaging member, 
 ii) a molded shaving aid, and 
 iii) a combination thereof; 
   c) applying a second composition to said contacted surface to form a treated surface,   d) wherein at least one of said first composition, said hair removal device, and said second composition comprises a pyrithione source.   
     
     
         2 ) The method of  claim 1 , wherein said pyrithione source is selected from a group consisting of zinc pyrithione, sodium pyrithione, pyrithione acid, dipyrithione, chitonsan pyrithione, magnesium disulfide pyrithione, and combinations thereof. 
     
     
         3 ) The method of  claim 1 , wherein said pyrithione source is at a level of from about 0.01% to about 5%, by weight of said composition. 
     
     
         4 ) The method of  claim 1 , wherein said pyrithione source comprises a platelet zinc pyrithione (platelet ZPT), wherein the platelet ZPT comprises a mean particle diameter of about 0.5 microns to about 10 microns, a median particle diameter of about 0.5 microns to about 10 microns, and a thickness of about 0.6 microns to about 15 microns. 
     
     
         5 ) The method of  claim 4 , wherein the mean particle diameter of the platelet ZPT is about 1 micron to about 5 microns. 
     
     
         6 ) The method of  claim 4 , wherein the median particle diameter of the platelet ZPT is about 0.6 microns to about 0.7 microns. 
     
     
         7 ) The method of  claim 1 , wherein the composition which comprises the pyrithione source also comprises an additional antibacterial agent selected from the group consisting of triclocarban; triclosan; a halogenated diphenylether; hexachlorophene; 3,4,5-tribromosalicylanilide; salts of 2-pyridinethiol-1-oxide; and mixtures thereof. 
     
     
         8 ) The method of  claim 1 , wherein more than one of said first composition, said at least one skin engaging member, said at least one molded shaving aid, and said second composition comprises a pyrithione source. 
     
     
         9 ) The method of  claim 1 , wherein said hair removal device comprises at least one blade intermediate between two molded shaving aids. 
     
     
         10 ) The method of  claim 9 , wherein both of said two molded shaving aids comprise a pyrithione source. 
     
     
         11 ) The method of  claim 1 , further comprising applying a pre-treatment composition to said portion of skin prior to the application of said first composition. 
     
     
         12 ) A method of treating skin comprising:
 a) applying a first composition to a portion of skin to form a prepared surface; and   b) contacting said prepared surface with a shaving razor to form a contacted surface, wherein said shaving razor comprises a razor cartridge comprising at least one skin engaging member, at least one molded shaving aid, and a combination thereof;
 applying a second composition to said contacted surface to form a treated surface,., 
 wherein said second composition comprises a zinc pyrithione. 
   
     
     
         13 ) The method of  claim 12 , wherein at least one of said first composition, said at least one skin engaging member, and said at least one molded shaving aid comprises a pyrithione source selected from a group consisting of zinc pyrithione, sodium pyrithione, pyrithione acid, dipyrithione, chitonsan pyrithione, magnesium disulfide pyrithione, and combinations thereof. 
     
     
         14 ) The method of  claim 12 , further comprising a step of rinsing said contacted surface before said step of applying said second composition. 
     
     
         15 ) The method of  claim 12 , wherein said first composition is supplied by a reservoir provided along with said razor. 
     
     
         16 ) The method of  claim 15 , wherein said step of applying said first composition and said step of contacting said prepared surface happen concurrently. 
     
     
         17 ) The method of  claim 12 , wherein said second composition is supplied by a reservoir provided along with said razor. 
     
     
         18 ) The method of  claim 12 , wherein said shaving razor is a composition dispensing device having at least one reservoir for containing a composition. 
     
     
         19 ) The method of  claim 12 , wherein said first composition is a shave preparation and said second composition is a post shave lotion or moisturizer.
