I got this shortly after my baby was born, and aside from the fact that the bottle had a leak when I opened the box - not the product problem, of course, but still disappointing after paying so much money for it, I used it and saw absolutely no difference, effect or any evidence that I had used anything at all, even after the entire bottle was gone. It didn't last long either, as the bottle is a pump, and it looks a lot more of a generous dose than you are actually getting. As wonderful and effective as mama mio oil was to prevent the stretch marks, this one was extremely disappointing waste of money. Too bad with a newborn I didn't have the time to deal with returns. Bottom line - it didn't smooth or tighten anything.
