         8 . The greaseless analgesic composition of  claim 7  wherein said low molecular weight silicone comprises a cyclomethicone selected from the group consisting of octylmethylcyclotetrasiloxane, hexamethylcyclotrisiloxane and decamethylcyclopentasiloxane. 
     
     
         9 . The greaseless analgesic composition of  claim 6  wherein said low molecular weight silicone comprises a non-cyclic silicone selected from the group consisting of hexamethyldisiloxane and low molecular weight dimethicone. 
     
     
         10 . The greaseless analgesic composition of  claim 1  comprising a high molecular weight dimethicone component, a volatile low molecular weight component, and at least one analgesic component selected from the group consisting of methyl salicylate, salicylic acid, a salicylic acid derivative, camphor, menthol, eucalyptus oil and capsaicin. 
     
     
         11 . The greaseless analgesic composition of  claim 10  comprising at least two analgesic components selected from the group consisting of methyl salicylate, salicylic acid, a salicylic acid derivative, camphor, menthol, eucalyptus oil and capsaicin. 
     
     
         12 . The greaseless analgesic composition of  claim 1  comprising a capsaicin component dissolved in a alkyl fluid. 
     
     
         13 . The greaseless analgesic composition of  claim 12  comprising at least one low molecular weight silicone component. 
     
     
         14 . The greaseless analgesic composition of  claim 1 , in the form of a serum having a viscosity of from about 0.1 centistokes to about 3500 centistokes. 
     
     
         15 . A method of reducing pain in a mammal, comprising applying to a skin surface of said mammal a composition comprising the composition of  claim 1 , and permitting said applied composition to dry on said skin surface, wherein said high molecular weight silicone component forms a substantially clear, water-resistant barrier on said skin surface after drying. 
     
     
         16 . A topical analgesic composition comprising at least one high molecular weight dimethicone component having a molecular weight between about 100,000 Da and 100,000,000 Da, and at least one analgesic component comprising an agent selected from the group consisting of selected from the group consisting of: methyl salicylate, salicylic acid, a salicylic acid derivative, camphor, menthol, eucalyptus oil, and capsaicin, wherein the composition is substantially anhydrous, greaseless, and substantially clear or translucent.
