I use lotion, but stretch marks are totally heredity. The lotion will only help minimize the itching with stretching skin. Anyone who tells you that lotion, even heavy cream, will PREVENT stretch marks is blowing smoke up your ass.
If mom got them, chances are, you will get them too. Also, if you got stretch marks during puberty, chances are, you will get some when PG too.
I expect to get some, it sucks, but I bet I'll get some on my hips and possibly boobage and inner thighs - that is where I got a few during puberty (although, you can't really see them now). I do not think my mom had any though .... but I can't remember exactly.
