I call week 4 the half way point because Rodan+Fields comes with a 60 day "empty jar" return policy on their products. So if I decide after 8 weeks I'm not seeing a difference, I get my money back. I'd have to say that the lines around my eyes and mouth are much less. I also feel like my skin tone is better. I think I'm starting to see some changes in my eyes as well. I've been using the Rodan+Fields Multi Function eye cream for two weeks now, and while looking in the mirror I don't feel like I see much of a difference, but when I put my "before and after" two week pictures side by side, I think I am starting to see a change. What about you? Please let me know what you think, I'm really curious....you know, sometimes it's hard to see the forest for the trees.
