I had moderate acne for a few years so my dermatologist put me on doxycycline then minocycline & my face cleared up but 2-3 months after, acne came back. I currently use Epiduo and my face is clear for the most part right now but I do still get acne, especially on my chin around that time of the month. I get some whiteheads on my forehead & sometimes nodules on my temples. I think some acne I get could be because of makeup I use but could this be hormonal acne? (My period is not always regular).
