I don't think I've heard good things from bio oil. I would try Aveeno Lotion or Coconut oil :) I love stretch marks! I think they are so beautiful!! You should be proud of them hun!! They are there because you had you beautiful son :) Don't worry they will fade to white eventually :) I had some from when I was a kid because I put on some weight and grew a lot. They eventually faded and turned white...and restretched again when I lost some weight in my first trimester :) I'm not at all bothered about them :) @jade_17 xx
