Embarrass, The dark line flanking the vertical part of your scar is pigment that is in the skin that used to be adjacent to the areola when it was lower on your breast. Usually this skin is normal color before surgery so the pigment potential cannot be readily detected, but this is the area where the pigment darkened making the areola diameter look larger if you have had a pregnancy, or more, in the past. The inflammation that is normal with healing simulates the pigment-producing melanocyte cells to produce and deposit pigment after the surgery, resulting in what is termed post-inflammatory hyperpigmentation. It can be easily addressed by re-excising the scars more widely and reclosing the wounds. This can be done under local anesthesia in many situations. Tattooing is not going to help this. I hope that this helps. Best wishes, Tom DeWire, MD, FACS Richmond, VA
