My mother is 66 and looks like she's in her early 50's. She's done a lot of research on the best anti-aging creams and for the past several years she's used the new Oil of Olay stuff - the face serum, eye serum and microsculpting cream. She says the stuff works great and she's recently started the Oil of Olay pro-X.
She's never much of a sunscreen user, but I've noticed she's always protecting her face with hats and I think that's been major factor for her young looking skin.
