Scar cream for stretch marks?

Karen
Hey ladies! Looking for suggestions here. I have a glorious, glorious halo of stretch marks from this pregnancy. Some of the ones around my waistline are huge- at least 3 inches long and an inch wide. The skin is so weak that even having elastic touching them is so itchy and uncomfortable. 
Are there any good creams out there that strengthen the skin up a little bit? Anything you suggest would be awesome!
