the best thing to use is coco butter. every one says it works. people use it all the time and their stretch marks just go away. it may take a while but it does work.

Cocoa butter has been suggested by some members of the alternative medicine community as a stretch mark inhibitor for women about to go through a pregnancy. Work cocoa butter into your skin, especially around the hips, thighs, stomach, and butt, each day after your morning shower and before bed. The same regiment can be used to cure or prevent stretch marks in anyone who expects to experience exceptional skin tension, like that caused by a pregnancy.
