I absolutely fell in love with this product soon as it came out. I tried it alone & under my concealer and I was amazed on how well it brighten under my eye, which are very dark to begin with. I think its a must have if your into the whole "Kim K Look" It keeps your concealer on until you take it off! Even though it says "Hydrating" it does not look or feel shiny. It's a life saver!
