Acne problems

Chloe • Hullo
I'm 18 years old and for the past few years I've had pretty bad acne around my forehead area. All my friends my age have clear skin but I still have acne. I've tried nearly everything. I try a new product and it works for a while but then my skin starts to break out again and I need to switch to another product. 
Do any of you guys have recommendations about what I can do to clear up my skin?
