         11 . The method of  claim 2 , wherein the hydrophobic solvent comprises soybean oil, coconut oil, cyclomethicone, and/or mineral oil. 
     
     
         12 . The method of  claim 2 , wherein the hydrophobic solvent is present at a concentration from about 60% to about 95% by weight of the composition. 
     
     
         13 . The method of  claim 2 , wherein the foam composition further comprises a silicon dioxide. 
     
     
         14 . The method of  claim 2 , wherein the wax comprises beeswax and/or hydrogenated castor oil. 
     
     
         15 . The method of  claim 2 , wherein the wax comprises beeswax and hydrogenated castor oil. 
     
     
         16 . The method of  claim 15 , wherein the beeswax and hydrogenated castor oil are at a ratio of about 5:1 to about 1:1. 
     
     
         17 . The method of  claim 15 , wherein the beeswax and hydrogenated castor oil are at a ratio of about 2:1 to about 1:1. 
     
     
         18 . The method of  claim 15 , wherein the beeswax and hydrogenated castor oil are at a ratio of about 4:3. 
     
     
         19 . The method of  claim 15 , wherein the beeswax and hydrogenated castor oil are at a ratio of about 1:1. 
     
     
         20 . The method of  claim 2 , wherein the composition has an Aw value of less than about 0.5. 
     
     
         21 . A method of treating rosacea, comprising administrating a foam composition comprising:
 a) a combination of at least one fatty alcohol and at least one wax; or a combination of at least one fatty alcohol, at least one fatty acid, and at least one wax;   b) at least one hydrophobic solvent; and   c) a minocycline at a concentration between about 0.2% and about 20% by weight of the composition;   wherein the composition is free of surfactant;   wherein the composition is essentially waterless; and   wherein the ratio of (1) fatty alcohol to wax or (2) fatty alcohol and fatty acid to wax is between about 1:3 and about 3:1.   
     
     
         22 . The method of  claim 21 , wherein the minocycline is present in a free base form, a hydrate form, a salt form, or a complex form.
