I hav a stretching mark just below my belly button because i'm fat. if i lose weight, will the mark disappear or do i hav to use medical cream?

No.: There is a laser procedure called i-lipo which can make the stretch marks less visible. See if you can google a site that offers it near you. It can also help decrease the fat in areas difficult to lose. It really works!

Stretch mark: Stretch marks are usually permanent. Creams are of not much help either. Over time the stretch mark may fade but not disappear altogether.
