Stretch Mark Predictor?

SposaBellarina

Hey ladies, is there any way to determine if you're predisposed to stretch marks (genetics, skin type, complexion, etc)? I am 23 weeks and my OB's nurse told me the tattoo on my hip would be fine.  When I asked her how she knew that, she just said, "you'll be fine," again.  I think she's pretty knowledgeable & reliable in general, just wondering how she could know that... And also keeping my fingers crossed and applying Mustela daily!
