I am 57 and have managed to keep wrinkles and dark circles away by using a German baby cream called Penaten Creme every night under my eyes. I've done this for over 35 years and I have hardly any wrinkles around my eyes and no dark areas at all. You can also use any good thick baby creme / zinc creme you get here in the UK , or if your eyes are puffy - try using one of the top modelling secrets - hemorrhoid creme such as Anusol under your makeup during the day. Sounds ridiculous, but these do really work and are far less expensive than most of the specific eye creams sold by the cosmetics companies!
