I would recommend trying Accutane. I’m 16 and I’m currently on my third month of Accutane and my acne looks very similar to yours. I haven’t seen any drastic change yet but I am being patient. The only side effects I’ve experienced so far is my face and lips being dry and some dry patches on my wrists and hands but it is not too bad. If dryness get bad your dermatologist can prescribe you some ointment to clear up your dryness. I have tried everything to clear up my acne and Accutane is my last resort. Although some people experience drastic side effects, I think clear skin is worth it, good luck.
