First of all, after a shower, use a super soft and absorbent towel, like these Egyptian cotton towels from I love Linen. Don't rush in drying your skin but be delicate doing it. I have seen skin that was treated roughly, and the elastine you have got in your skin will break and leave your skin sagging.
First of all Sun is your skins worst enemy, I know a woman who applys sunblock everyday and now at the age of 60, she looks amazing and has tight smooth skin.
Apply handcreme to your hands, at least a few times a week. Really...You can tell the age of a woman by looking to their hands as cosmetic surgery is not able to be done to hands.
