I’m either looking for some sort of treatment or acne products that would be helpful.

Allright, so i have many fairly bad acne scars from breakouts about a year ago, i’m 16 now and my acne has cleared up alot more, i still get minor breakouts though, how can i remove the scars without causing a more severe breakout from scar treatment?
I also have minor cystic acne, it’s not visible, but will scar treatments make that worse? and how could i get rid of the cystic acne without something as serious as accutane?

P.S the scars are fairly bad, some indent into my forehead

I’ve had acne on my back for a couple of years now. I thought it would go away over the years but it seems that it won’t go away. What’s the best treatment for it?
