What gets rid of or at least highly lightens pregnancy stretch marks?

Ok I am about to be 8 months pregnant and I am starting to get stretch marks, My mom always told me that not to scratch that it will give you stretch marks, well I listened and haven't been scratching, instead I use palmer's cocoa er soothing oil for itchy skin, but anyways, I know their are lots of products out there but what actually works? and is there even any home remedies that I can try too? please help...I don't want to live with stretch marks the rest of my life...
