Mine lightened a little after massaging a concentrated vitimin E cream into them for about a month. But honestly I think they've become least noticeable due to weight loss!
I have a bunch of scars over different areas of my body, some stretch marks.. and some not. But really it doesn't bother me anymore, you can only do what you can, and try and accept what you can't. Most of the clothing I like to wear hides them anyway. And anyone worth having around me isn't going to care if I've got a few stretch marks once I've lost my weight. If they have any sort of a heart at all they'll be more impressed that I'm changing what I can change
But, obviously as we all know for personal reasons, even if no one else sees it, there are still things that bug us. So yes - bio oil, vitimin E, a good massage, continued weight loss and hope for the best!
