Yours looks a lot like mine unfortunately  painful and large area cyst type acne. Does yours ever come to the surface or not really? Min doesn't

I wish I was help but I'm still trying to figure mine out! Let me know if you find anything that helps..

I really recommend trying "the oil cleansing method" for this type of acne. You can research on YouTube and see the amazing results. Try toning with Apple cider vinegar, and moisturizing with coconut oil. Also, the most important thing is focusing on what's going on within. The supplements I recommend most are milk thistle, oil of oregano, turmeric and garlic. Good luck, and let me know if you have any questions
