Why is my scar outside my belly button after Tummy tuck? (photos)

The umbilicus can be the critical issue after tummy tuck as this is the scar that cannot be easily concealed. Your result appears to have turned out very well, though the umbilical scar is a challenge. There are many ways to set in the umbilicus during tummy tuck, and revision questions are frequently posted. Pressure, massage and silicone sheet can help things turn for the better, with a wait and see approach as you continue to heal.

Thank you very much for your question, and for providing the pictures.Overall, you seem to have a pleasing shape to your torso, and incisions which will go on to heal well once the redness has faded.  Regarding your umbilicus, every surgeon has their own technique regarding how to shape it.  I would discuss the appearance with your surgeon.  Belly buttons can be difficult to make smaller.  I would wait until your incisions aren't red (therefore they will be less noticeable), before making any decisions on undergoing a revision.  Best of luck!
