This is the most amazing product I have ever used. Why? Because it actually does what it says it's going to do. If you have dark circles under your eyes and you've used everything on the market and in your kitchen to try to get rid of them, TRY THIS!!! On the package it says to apply it every night before bed. I was so desparate that I used it every night and every morning. After about a week and a half, I thought that the circles were fading, but I was sure I was just convincing myself. Then my boyfriend made a comment one day, something about my eyes looking brighter or shinier or something like that and I was like WOW!!!!! If your boyfriend notices, it must be working. This product is well worth the price. It really works.
