No, a tummy tuck won’t do anything for stretch marks. Obviously, any stretch marks on the skin that is removed are gone, but the rest will be just as much there as before. They may just change location a bit, moving with the skin. I still have about half of the stretch marks from the triplets. I have a new batch from my youngest, born after the tummy tuck, but they are very light. They are horizontal, instead of vertical like my other stretch marks, and they are all above my belly button, instead of beside or below it.
