As a woman I find that it is a bit harder to stay looking younger.
But for me I wash my face every evening, with soap and water (neutrogena) I have found this is the best soap for using on women faces.
I drink lots of water, at least 8 ozs. 4 times a day. plenty of beauty sleep
being in a stress free environment helps as we all know that stress develops wrinkles, as does frowning alot. So staying in a good mood and being cheerful I think helps with looking and even staying young at heart in general.
Looking young anyways is really alot of hype to me so it's just a matter of living well and taking care of your body.
