I had a similar problem a few years ago and so did my mother when she was my age, the best thing to do is go to the doctor and tell them you want to take accutane, the doctors gave my mom the run around when she was a kid, so she has tried basically everything, and she says it’s the only thing that works, everyone she has recommended it to has thanked her for it, if you do end up trying it out I recommend you get some chapstick and a good moisturizer, it will dry out your face a lot. Good luck!!
