Stretch marks are inevitable depending on your genetic make up, for myself-unfortunately, I know they'll be on their way (boo), as I have had them before with weight gain in the past. That still doesn't stop me from moisturizing, however. I use bio oil or Palmer's cocoa butter oil repair therapy stuff, a Q10 firming lotion on my thighs, arms and hips (I've used this for years, though), and cocoa butter lotion. Never hurts to keep your skin hydrated and healthy though, not only through pregnancy, but as a lifetime regime!! Haha, we only get one skin, may as well keep it nice, right?!
