First thing I want to get off my chest is, why would you package an expensive eye cream in a little packet??? I opened my packet to use some at night, have a bunch left to keep trying, next morning the top layer of cream was dried and rubbery. Unusable. We could get a lot more out of the product if it came well packaged. That being said, the cream felt amazing on my skin. While I did not really notice my dark circles looking brighter after 2 uses, my skin definitely looks healthier and more moisturized. Given a better sample to try over a few days, I bet this would improve my under-eye area. Seems like a great product.
