Options for Abdominal Surgery Scar Revision?

The indented scars can be improved with percutaneous scar release and scar revision surgery. I would not anticipate a tummy tuck later as that may or may not be needed. 

Fortunately, both scars are positioned
so that a full tummy tuck will remove both. Like others mentioned, you need to
wait until you’re done with having children. Thanks for sharing.

It is good news that your treatment was a success. Given the current and relatively minor problem, by comparison, the options for improvement are limited
As you have suggested, I would recommend deferring treatment until completion of childbirth. It is likely you could replace both scars with one that is located on you lower abdomen and potentially concealable beneath a undergarment.
Your scar is reasonably good at this time and the marginal benefit you could obtain from interventions is only likely to be minimal. Therefore, I cannot recommend any treatment at this time that would achieve any substantial improvement.
