Wrinkle cream

I just blogged about in my previous post about a cousin who is wanting me to buy wrinkle cream for her. I was so confused because i can't really find the product that guaranted their effectiveness. We all know there are hundreds of products in market today that are buzzing around and its very impossible to determine which cream work. I don't want to spend my money for uneffective cream or got scammed over this. I have a friend who complain about the wrinkle cream she bought at our local store that didn't even work and paid almost $100 for it. That just a big no-no to me. I appreciate if someone can tell me about these rated and best wrinkle cream available today.
