How Can I Fix Bad Dermasanding Results?

Im a 28 year old female that had dermasanding done to help improve minor shallow acne marks on my chin in the peri-oral region. It has been 3 months now, and the skin is very dry, shiny (waxy) appearance, very noticeable texture difference, still has redness, and has created marionette lines that weren't there before (the skin is sunken in where the dermasanding was performed). I was wondering if there was anything I can do or is this something I am going to have to live with.
