So I've been using the regimen for roughly 7 years with amazing results. It's the only program that had really worked for me. I had moderate to severe acne for 10 years prior, using every medicine known to man including accutane on 3 separate occasions. Over the course of the 7 years i have had some breakouts but it would usually be because i wasn't using the proper amount of BP. Usually when i would ramp it back up it would clear up in a few days. Over the past week i have been having some serious breakouts. I went from a completely clear face to having some pretty substantial acne. I had a fresh bottle overnighted to me thinking maybe the bottle i was using had lost some effectiveness (the cap had broken off), but I'm still breaking out. Is it likely the BP is no longer an effective option for me? I would really hate to have to go back to the dermatologist considering i had very limited results using prescription medication. Its just frustrating having to fight again for something i thought was in my past. Has anybody had the BP stop working for a period of time and it cleared back up with persistent use?
