Stretch mark cream

Grace

What is the type of stretch mark cream you all use ? I have been using one but it doesn't seem to be working .. Are there any that actually work or actually help ? The first time I had a girl and got stretch marks on my butt but this time I'm having a boy and he is a lot bigger and growing a lot faster than what she was and I'm getting them all over my stomach. Any suggestions would help . Thank you!
