I have it and I can honestly say that it does NOT work on dark circles although it does help smooth out lines just alittle bit. I usually put it on with the concelear on top and it helps it go on alittle smoother. I guess it works just like any other eye cream so you might want to check out other brands that help with circles. They did tell me it was for this and I got suckered into buying it and found that it didn't work for that.
