Have any published studies been done on anti-aging creams?

I think most can make the anti-aging claim just because they have sun-block in them, but is there any other ingredients that have been scientifically tested?Have any published studies been done on anti-aging creams?
I think they test Retin A -





I have been using Arbonne's nutrimin c re9 regime


and it's been tested - and it's made with botanicals and 9 key ';healthy'; things that is under patent pending for being the ';best'; aging regime on the market. For me I wouldn't want someone spewing those ';words'; if it didn't work.
