Hi China Doll, It's worth starting to use a light moisturiser now even though you don't have any wrinkles. Prevention is better than a cure!
I use Liz Earle products and she does a light moisturiser which is excellent. I'm 47 (48 in a month's time) and people tell me I definitely don't look it, most of my friends in the school playground are 10 years younger than me and they always assumed I was the same age!

Also drink lot's of water, keep out of the sun, don't smoke, and ALWAYS wear sunglasses when you're in bright light - if you screw up your eyes those lines will set into wrinkles by you're late 30's. I've naturally always done these things as I'm fair skinned but it's paying off in spades now.
No cream will get rid of wrinkles once you have them but they will stop progress so start now.
