I’ve been using Clinique’s Even Better Eyes Dark Circle Corrector for a month. I got it from December’s MAC warehouse sale as part of a pack with Clinique’s dark spot corrector for $30. After the first week, I saw a difference. My dark circles were getting better, but then I had a few late nights and they started to show up again. With a good night’s sleep and staying hydrated, I do notice that the dark circles aren’t as bad and my under eye area is softer and more hydrated than before. I also like the metal applicator, it feels nice and cool under my eyes. At $55 (the normal retail price), I don’t know if I’d buy full price and I’m sure there are cheaper other creams that do just as well, but for less than $30 at the sale, this was a great deal.
