I'm a big fan of Olay products! I started using them in my teens and now I'm 36. I'm always told I look like I'm in my mid 20's, THANKS OLAY! So, I decided to purchase this eye cream last weekend because, we'll, it's time. I have very minimal crows feet and minor lines under my eyes when I smile. I was very surprised when I saw an instant change in the dark circles! I always have them, but I cover them very well. But they are almost gone! Even my eyelids seem filled out, much less droopy!! Today makes day 5 using this product! I'm very happy so far! I'm glad I added it to my skin care regimen, I should have tried it months ago!
