How can I get rid of crepey skin after a tummy tuck? (Photos)

Had a tummy tuck with major muscle repair last year. These stretch marks were above my belly button and when they got pulled down they pulled and also got crepey. When i stretch my stomach skin, to me it looks better. What procedure can be done to make that happen? I was looking at bodytite but is that the best option. I also do not currently have a belly button, it will be made at a later time.
