see if your insurance will cover regular retin-A that has a generic form called tretrinonin(sp?) My insurance wont cover Retin-A Micro or Differin unless you've tried the cheaper version. In my case the regular retin-A works great and is only $10 for a good sized tube. Warning regular retin-A is a little bit harsher on the skin than Micro, so if you have sensitive skin maybe its not the best choice but if your really oily like me then it works great. Also, look into spironolactone it is working amazing for me and its cheap, most insurance would cover it even if they don't its still not that expensive. It has very few side effects as well.
