What kind of acne products has work better? for my teen 13 boy?

I am 25 and have suffered with acne for 10 years now. I have tried everything, including all the expensive stuff. I was at the end of my ropes. I picked up neutrogena pink grapfruit acne face wash caused I liked the smell and I needed something to wash my face with. i never really thought it would work. It took about a month but I am happy to say I am acne free and Its the best feeling ever. The best part, it only costs me about 7 bucks a bottle.
