Sadly there is nothing you can do to prevent them. If you're going to get them, you're going to get them. They are genetic so if your mom or grandma has them chances are you will as well. The palmers will make your belly feel nice though especially if it gets itchy or dry!
I've been wondering the same but I been using curel pregnancy lotion
Theres nothing you can do about them. You cant prevent them at all. Over time they will turn from bright purple to a silvery color. Don't dwell on them to much. I got them with my first pregnancy and never got them again. And i have 4 kids:)
my mom had severe stretch marks...im on my second pregnancy and so far everything looks good!
I'm on my second, I use Olay 24 hour moisture lotion, I love it and I've used it with both of my preg, I only have gotten a couple small stretch marks on my sides. I just didn't like the palmers kind. Cocoa butter lotions just don't moisturize well enough for me lol
