I just want to say that I know I've heard that stretch marks happen if they run in your family no matter what. BUT before pregnancy I had stretch marks on my breasts and they have doubled in size. I never used anything for stretch marks before but in the last three months I've used pure shea butter on my body after I shower and my stretch marks are GONE!!!! So don't let anyone tell you that there's nothing you can do to prevent or eliminate stretch marks!
