Hi, I've been suffering with problematic skin since I was 12, I am currently 22. I've tried different products throughout the years and also have been to the Dr's numerous times. I've tried pretty much most of the prescribed topical creams and lotions and was also put on birth control to help keep my hormones in check. I was also referred to a dermatologist, but he didn't help me at all and kept trying to sell his own acne regime to me (as I was 17 at the time and the regime was expensive he suggested for me and my sister to buy it together and share it). Nothing has ever really helped and I feel like for the past 10 years my face has never been clear and I can't even remember what it feels like to wake up with  good skin. I was diagnosed with PCOS, so my acne is hormonal. 
I'm currently at the stage where i'm not really sure whether the marks on my face are acne/spots or whether they are acne scars or hyper-pigmentation. 
Therefore i'm kind of confused as to what products to purchase to help my skin. I feel like just purchasing acne treatment stuff wouldn't help me if a majority of the marks are scars or hyper-pigmentation. 

I'm just wondering whether someone can help me out in determining what they are so that I can buy suitable products? 
Thanks for any help you guys can offer
