I Am A 21 Year Old Female. As A Teenager

I am a 21 year old female. As a teenager I never had a problem with acne. I had a couple pimples around my period but that was all. When I was 20 I starting get the depo injection. I was on it for 9 months and I started getting moderate breakouts. I got one more injection because my doctor wasn't sure if the shot was to blame. For that whole three months I had constant acne. He switched me to quasense about two weeks in and seeing no improvements I got impatient and my doctor put me on minocycline 100mg once daily. I have been taking the birth control for 8 weeks and mono cyclone for about 6. I have been religiously following a skin care regimen that includes 2% salicycic acid twice daily and 3.5% benzoyl peroxcide at night. I've seen minor improvement but still have breakouts on my jawline, chin, parts of my cheeks and a little on my forehead. I have an appointment with a derm in two months but I'm feeling hopeless and will take any advice I can get to improve my skin before then. My pimples range from deep cystic to normal white head forming pimples
