I was under the assumption that this was a concealer when I first got it in a kit I bought from my local rep. So when it didn't cover the darkness under my eyes, I was ticked off. Then I read what it actually is and have continued to use it morning and night. What a difference!! Not even a small difference, the darkness under my eyes has drastically been reduced. It's a white/grey cream and you only need to use a little bit to cover the under eye area. Absorbs super quickly and gets to work immediately. I've never had a product give me such amazing and drastic results so fast. Cannot recommend this enough!
