Train tracks aroun belly button one year post? (photo)

The scar is from the superficial sutures that were placed at the time of your surgery. The earlier these are removed, the less chance of 'Train track' scars. I disagree with the physicians who recommend a tattoo. Dermabrasion or Collagen Induction Treatment with a series of microneedling (I use the DermaPen) will help camouflage these scars nicely. It would also help with any residual stretch marks that may remain on the skin after the tummy tuck. DO NOT get a tattoo unless you really want one in this area.

Dear Patient,this is an unfortunate scar, but it can be revised under local in the office. the final results should be a line. if you still do not like it, then 6 months or a year later, you can always get a tattoo ?good luck and consult with a Board Certified Plastic Surgeon in your area,Florence Mussat

The scar around the umbilicus is the most visible portion of an abdominoplasty.  Once the scar has turned white it will not change.  The key would have been to remove the sutures early.  In your case a minor surgical revision would significantly improve your result.
