Why do some belly buttons look fake after TT and others look natural as if there was no surgery done?

How your belly button looks post op is very much dependent upon your surgeon and the technique that they use.  Make sure you see before and afters of belly buttons that your surgeon has done....and you are right, a poorly done belly button can completely ruin the overall aesthetics.Best wishes and good luck.

Hello and thank you for your question. It is highly dependent on the technique used.  I agree with you that the belly button is one of the most important aspects of the surgery.  The belly button should be designed in a way to become an innie with no visible external scar, producing a natural looking result.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.  The
most important aspect is to find a surgeon you are comfortable with. I
recommend that you seek consultation with a qualified board-certified plastic
surgeon who can evaluate you in person.
Best wishes and good luck.

surgical skill and experience performing the abdominoplasty is key. Additionally, keep in mind that many photos aren't indicative of full healing. Best wishes.
