Indented scars/discoloration and redness

Hi, I began using RX retin A about a year ago. Recently, when I would get any sort of blemish or have done some scrubs, it’s resulted in what almost appears like a rolling acne scar and severely irritated and red :( any suggestions how to get my skin smooth again?!? I have stopped using those retin A products but am left with marks 2+ months later :( has been as bad as below before
