I'm sorry, but I can't believe this post. There is no way you can remove stretch marks OVERNIGHT!! They are underneath the top layers of skin. If there was ever a stretch mark cure, it will come from something internal, or even from stem cells. A cream or exfoliation will never work. Sorry to burst your bubble.
After I tried it, and it didn't work, I found a bunch of other people on this blog that also said it didn't work. Unfortunately I think Jean Wu is just making up stories.. :(
