How long does the Instant Facelift Serum effect last?

I keep watching these miraculous testings with the Instant Facelift Serum and the results are unbelievably good. I would love to buy this product but I want to make sure it's worth the money. How long does the effect last? Minutes, an hour, a day? It can't last more than a day, that's for sure.
