My new favorite eye cream is Kiehl's Avocado Eye Treatment. My under eyes were getting dry using the Clarins one mentioned in Part 1. If you are in need of major hydration then step into this! I would recommend waiting a few minutes before putting anything over it (i.e., concealer) as its a takes a while to soak in. It is only $25.00 at your nearest department store and so far has been great.
I do not know if it will help with long term under eye aging or if it has any ingredients to help your under eyes but so far I am hooked!
