I've been using retinol overnight for large pores and blackheads, but I have a burn mark in the area that hasn't entirely faded from a failed DIY chemical peel a year ago. I wash once daily with Cetaphil. Photos are attached showing the skin and discoloration. Any advice would be greatly appreciated. I've suffered horrible psychological effects from acne and scars for nearly a decade.. I do intend to see a professional within the next few months. I'm willing to spend thousands for a procedure.
