I swear by the rule of always keeping your face protected by the sun. I wear a hat and sunnies, sunscreen, my face is always super pale but i'm yet to get a wrinkle and ppl always tell me they thought I was 18, still get asked for I.D hahaha
I also have used a mosituriser every day since I was about 16, I think skin is more likely to wrinkle if it gets too dry.
I'm using moogoo on my face right now, just the udder cream.
I think past posters are right, a healthy diet, plenty of water and exercise is the key as well as sun protection. Why not try a cheap vitamin E cream or something? Quick and easy
