Yeah I've been using cocoa butter four times a day (a little over the top I know haha) But I'm going to wait until after I deliver and the stretch marks calm down and use mederma, a friend of mine used it and you honestly can HARDLY tell she had stretch marks so I'm going to try that!
Yeah I agree with GRose moisturizing should help, it helps me.
I know mine hurt when I was pregnant with Noah, they dont this time around cause they haven't gotten any worse (yet), it's just from all the stretching. Make sure you are moisturizing twice a day, if not more. If it gets really bad just mention it to your doctor.
