Supposedly nothing can prevent stretch marks, they are reportedly genetic. But I’m all about helping my genes out in any way possible. My cousin actually sent me this as a gift as I entered my second trimester. I’m happy to report – no stretch marks! But on top of that, my stomach was getting really itchy as the skin stretched and dried out a bit, the Bio-Oil made me feel so much better! I tried a few other lotions/salves but this one really hit the spot for me! You can buy it here.
