Some products take several months to work, but the fact that you ARE seeing improvement is enough to stay on it. I know exactly how you feel though. However it's better to have an improved complexion than to keep product hopping and possibly irritating your skin. Just hang in there a little bit longer!

Hey, I saw real improvement by months three, but I was still unhappy with the texture and redness of my skin, but I could tell it was working as I had pretty much no active spots, but it works at a different rate for everyone. I was also on birth control which I think also helped, so you could maybe look at that to help treat the hormonal side as well, but those two together have really helped, I'm going on month six and now and just trying to get rid of my post acne red marks and some slight scarring, still using my differin every night. I would keep using it if you find it is making a difference, it will keep working and getting better the longer you use it, but maybe see your doctor again to talk about something to use with the differin to help it work at but fast and stop your breakouts, good luck x
