How Much of my Stretch Marks Will Be Removed with a Tummy Tuck? (photo)

I'm skinny, with some extra skin from 2 pregnancy. The extra skin does not bother me as much as all the stretch marks. I have them mostly on my hips, and some under my belly button. The stretch marks on my hips are the most noticeable, so I would love to get rid of those at least. I'm 5'4 and 110 pounds, under 25 years old. I was hoping to get rid of most stretch marks and extra skin with a tummy tuck but would like to get some advice first.
