Help! Terrible hormonal acne

Has anyone dealt with hormonal acne a few months after coming off birth control? If so, how long did it last and did you find anything that helped? It's been 3 months for me and I've tried 4 different face regimes (proactive included). I started B5 with l - carnitine last week and I'm going to do a trial of dairy free this week.. hoping for any sort of improvement.
