Acne 😒

So I have had acne since I was 12. It all started with puberty, then probably cosmetic blemished from using my dirty fingers to apply makeup, etc. I am now 21 and still continue to break out. I have gone through phases with my lifestyle choices and right now I feel the healthiest I've been since I can remember. In college I drank and smoked and had glowing skin...4 years later I don't smoke, don't drink, and I eat plant based whole foods, homemade whole grain breads, rice, all non processed foods, and I'm a vegetarian. I drink plenty of water and I run almost every day. I feel amazing. But I am still breaking out. I'm just so frustrated and have no clue what it is. It comes and goes but is always still there. I went off of birth control about 8 months ago and I don't take any other medication except for ibuprofen maybe once a month. My cycle is regular, and my doctors say my blood tests are great. So I was wondering if anyone else suffers from acne, or used to and what worked for them. I have used doxycycline (it did work) proactiv (didn't work) changing my diet, sticking with a natural skin care line, applying makeup with sanitized tools, you name it. Please help! This photo shows all my bad breakouts. The top right is the clearest I've seen it and the bottom right is today, and that is pretty clear for me.
