Does this look normal after FDL tummy tuck, or is revision needed? (Photo)

This is a limit on how much skin can safely be removed at one time. Go back and discuss this with your surgeon. the vertical scar could be reopened and more could be removed. Perhaps you are a candidate for the reverse tuck too.

Dear Graceful984714,
I understand your concern and it is quite normal to be concerned about the outcome following a surgery. However, you are still in the early stages of the healing process.You will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues are still swollen. Once the swelling subsides, you will be able to see the final result of your surgery.

Congratulations on your impressive weight loss! It's still a little early to judge your results. With that being said it appears you may be bending forward a bit in your photo. When doing so you will always have some excess skin. If after 6-9 months you still have concerns you can consider a revision for further skin removal.
