back acne scars, help!!

i’m in dire need of some advice on how to deal with my back acne scars!!

I have medium tan skin and used to get incredibly bad acne on my back until a few months ago, however the marks are still there and it looks incredibly dark and splotchy on my skin. I’ve tried so many products but nothing seems to help.

I used to use the ordinary 10% 2-3x a week but it just made my skin incredibly dry.

My current body routine is:

african net rag with magnesium body wash

glow getter body butter with 0.1% retinol mixed into it

maybe once a week i use the glycolic acid now but thats it.

If anyone has success with fading dark marks on the body id sincerely appreciate it, any and all advice welcome!! :)
