Ever since I got pregnant I've gotten advised tons of times to lather up with: palmer's cocoa butter, bio oil, mustela, and many other brands I can't remember.

I have a good pile of stuff already but I wondered about product layering. My GF and another blogger said they layered products, but how do you really do that? Oil first? Then cream or cocoa butter? Do you wait in between?
I tried it tonight, but honestly feel like my clothes are all glued to me! But in the name of vanity, I will do whatever I can. An ounce of prevention is worth a pound of cure!

Any FAVES/Stretch Mark prevention MUST HAVES?
