I used a mustela stretch mark cream while pregnant. I never got any stretch marks. I am not sure if it works post pregnancy but you should check it out. It was the double action cream and ran about $40 a tube.
I used coconut oil after a shower, I do not have a single stretch mark. A women I know told me about it who has had 3 pregnancies, one was twins and she as well had no stretch marks.
Re: Stretch mark cream
Where can you find it? Target? CVS? Thanks!
