What acne product should i use if I have really bad acne?

I have tried a lot of acne medications and none of them have worked for me. Please help. I have a ton of acne what product should i use?

Proactiv is the best to use I have used it and have had flawless skin since then. If you having scarring do not worry it will slowly fade. Also remember it doesn’t work overnight but it makes a vast improvement. Google proactiv and you will find some sites that give you free trail sizes all you pay is shipping and handling
