Acne on your cheeks, chin and jawline are usually hormonal. 
(Hormones suck! It seems everything women have to deal with are because of them!)

On your forehead, nose and temples are usually just oily areas and are easier to treat.
(I had horrible acne when I was younger and have had a few times I have had to deal with it as an adult, so please know I am not just writing what I have read in a text book. I have dealt with this enough to have become very passionate about it.
what a sad thing to be passionate about-haha )
If you have any questions for me, please ask.
