OK don't hate me, but as you know I recently had a little baby boy, and I didn't get one single stretch mark (ya that's right)! I was looking in the mirror this morning after my shower and it dawned on me - I have no stretch marks (OMG)!
What's my secret? Bio Oil! Despite my skepticism I used it religiously everyday (what did I have to lose?) throughout my pregnancy in addition to moisturizer (Vaseline Intensive Care).
SO if you're preggers or thinking about getting pregnant get yourself some Bio Oil stat and start using it. You won't be disappointed.
