It has not been overnite, but I can honestly say that this cream works, it feels nice and has DRAMATICALLY reduced the lines that I have noticed around my eyes, nose and above my lips. I was considering buying one of those machines that exercise the face muscles, then i read a best selling book recommending a cream that cost a fortune, so found this cream on the internet with the same ingredients for 1/8th of the price and had it shipped to the UK. I am going to order quite a few more and recommend to my friends. And you dont need very much so it will last! Amazing stuff!!!!
