I had acne problem for like 5-6yrs. I did everything possible on mother earth. I saw many dermatologists but was never happy with my skin. The problem got worse when I saw a very well known dermatologist and he directly put me on some hormonal medications. My face got so bad that I could not even look myself in the mirror. After that, I stopped everything. I was hoping for it to get cured naturally. The bumps were gone in few days. But my skin wasn't the way I expected it to be for 2yrs and I was always worried about it. But from last 2-3 months I'm very happy with my skin. Here are some things that could help you. 
-Be super careful with what you eat. I won't say to cut off from junk food completely, everything is good in limit. Dairy foods are better to stay away from. 
-There are few Yoga practices specially for facial skin. Yoga helped me a lot with my skin. Do yoga first thing in the morning.
-I found that stress was the main factor in my case. I was always so conscious about the way I looked, I would always think people are staring at my acne, that caused low confidence and more stress and hence more pop outs. Try meditation and always think that acne is temporary and something so small can never define who you really are. 
-Some secondary things are good skin care routine. Though these are external measures, they can help with blackheads and feeling fresh. But treating the root cause would directly help with the extrnal stuff too. 
I hope it helps you. 
Be comfortable in your skin
Good luck!
