The one cream that has FDA approval for wrinkles is Retin-A. Everything else is unproven.
If you've got the dosh, use Green Cream.
It's a retinol cream (similar to retin-a, except not as intense/irritating) and works on wrinkles, lines, sun damage, blocked pores, acne. It pretty much gives you good skin.
I use it for acne, but all the other stuff is a bonus.
