Did anybody know some prevent product to stop the stretch skin after pregnancy. My mom is a pregnant, it's third time. She has very sensitive skin and now she don't now what to do?

During my pregnancy I used Palmer's Cocoa Butter lotion that is formulated to help prevent stretch marks. That was way before my gluten-free days, so definitely check the ingredients. But, as I recall, there weren't too many unknowns in there.
