Are you on birth control pills? If so what are you on?
Your best option is to get on a birth control pill that has a hormonal balance that helps acne (unlike the Mirena). Your best options are Yaz, Yasmin, BeYaz, Belara, Dianette, and as a last resort Ortho Cyclen. If you are on ANY other brand of birth control get off it.
Your second best option is to take some OTC supplements and change your diet to fix your hormone levels.The acne bootcamp page has a very detailed plan that tells you what supplements to take, what diet changes to make, and what cosmetics to use until your skin is clear.
