How can i effectively treat my acne?

I only break out on my chin/mouth area. Periodically I get several under the skin breakouts or a mild form of cystic acne. It's annoying and painful and I have always gotten this type. I use a good water based moisturizer and light makeup. I started a new birth control to level out my hormones which I ve been taking for a little over a month. If anyone has any good advice or skin care tips It would be appreciated! :) btw I have tried benzoyl peroxide...and so many others. They don't seem to help :/
