Hi Dr. I am desperate to find a fix for my purple butt. A couple of years ago I've had butt injections from a lady that is now nowhere to be found. She claims it was PMMA hydrogel that was injected and about a year ago I've noticed discolouration on the injected areas. A dermatologist told me it my skin was inflamed and needed to restore the skin with microneedling. Now my ass has two big purple circles. What is it ? Is it fixable? Please help !!!
