6 months post op - can the line of loose skin under my belly button be corrected? (photos)

You need to see a board certified plastic surgeon who has a great reputation for body contouring. This is obviously unacceptable and it's not due to your prior anatomy. Your surgeon is dishonest, and seemingly incompetent. I think I don't have to tell you to abandon your surgeon at this point.

Dear ostuff,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Your tummy can be fixed quite easily with the microcanulas under local. There is too much fat left behind in uneven areas all around your mid section. Lipo with bodytite and morpheus can fix this nicely.

It looks more than just loose skin. an examination is needed to see what can be done. Perhaps careful Renuvion treatment could help tighten the loose skin.
