What is the best wrinkle cream to buy?

OK I have to admit that the wrinkles are just starting to get the better of me. I HATE wrinkles. I have been using a wrinkle cream already, but it doesn't seem to be working which is really bumming me out. How the heck do you stay looking nice when you are in your fifties? I want so much to at least not look like one of those dogs with all the wrinkles so now I'm on the search for the best wrinkle cream. Anyone have any suggestions??
