@ddljohn-- Yes, vitamin E is good for stretch marks. There are even special vitamin E creams made for pregnant women for this purpose. If you had used it during your pregnancy, you might have been able to avoid stretch marks all together. Or at least, they wouldn't be so bad. It's never too late though, you can start using it now.
I think vitamin E is expensive. If you're on a budget, mix vitamin E oil with other oils like almond, olive oil or cocoa butter and apply it liberally on your stretch marks.
