At what age should I start using anti aging/anti wrinkle creams?

Can you answer I love you when you dont suck’s question about Anti-Aging?:

I’m 25 now and lately I’ve been thinking about starting a nightly routine of anti wrinkle / anti aging cream. Is it too soon or better to start now than when I actually have wrinkles? Also, what’s the best product to use?
