hi, acne on the cheeks may be linked to your lungs and liver. A diet high in sugar and dairy may caused acne on the left cheek whereas acne on your right cheek may be caused by a high sugar intake. Smoking may also be the cause of acne.....
Have you tried taking antibiotics??

^^I wouldn't be linking acne to the lungs and liver..

I know a lot of people notice an improvement in acne when they cut back on dairy and sugar. Dairy wasn't an option for me, but luckily I found something that helped my cystic acne.
