Beta hydroxy products and benzoyl peroxide products are cheap frangrance, free alcohol, reasonably priced and work.
See:cosmeticscop.com
If they dont work the cause is they are at the incorrect percentages and ph.
I would suggest prescribtion option such as azelaic acid, finacea, differin gel,retin a cream
