Welcome to most normal women's post-partum bodies! I have the wrinkly skin thing too -it's the one time in your life when your belly looks WORSE the more weight you lose! I feel I was lucky in the stretch-mark area given what I have seen on many women -only have them on my lower abdominal region where the wrinkly skin is -but it's still unattractive! Sorry to tell you -there are no "miracle creams" or treatments. The only way to rid yourself of them and have a smooth, showable tummy again is a tummy tuck!
***A note about celebrities and friends with smooth, flat tummies -most people who experience this got the luck of the draw in the gene pool! Some women are lucky enough to have a genetic makeup that doesn't seem to call for lots of stretch marks or stretched out tummies after pregnancy. As far as celebrities go -you would be SHOCKED at just how many DO have plastic surgery who swear they do NOT. They also have personal trainers, nutritionists and dieticians who help them throughout each pregnancy and immediately afterward. And then there are all of the airbrushed photos that look like they have no stretch marks when if you saw them in real life -you might be shocked. And yes -gaining too much weight at any time, especially during pregnancy, will leave you will less than desired tummy issues afterward, but the only way to rid yourself of them is plastic surgery. Just make sure you have lost all the weight you can and do a lot of ab exercises -particularly Pilates -to tighten everything as much as possible. However -once the skin is stretched out and has lost its elasticity -there are no exercises to help it.
