Stretch marks Lotions/Creams

So I've been using these stretch mark lotions and creams for the past four months. 3 or more times a day. I already had stretch marks on the sides of my butt- but those are from sports in highschool. I'm a very small person, so I don't want to risk stretching and busting like my mom did. She grew so fast that her stretch marks bled. So what products do you women use and swear by?
