Acne help! I have trouble spots on my cheeks that won't go away!?

i had really hideous acne on my neck and jaw from when i shaved for the first time and they didn't go away until i was in the tenth grade. I thank my doctor who prescribed me Adaplene cream, Clyndamicin gel and 10% sodium sulfacetamide 5% sulfur lotion. i aslo had to drink Minocyclin pills but they went away and the acne that waso n the rest of my face( nose, and a little on cheeks) was gone. i use the sulfur W/ sodium sulfacetamide on my face and the other two on my neck and jaw area. They went away in like 6 months but that was a huge relief from having the for like 3 and a half years.
