My can't-live-without is Natura Bisse Diamond Eye, and the Diamond Eye Serum (I'm older and need more than moisture) ... I recently tried the Kiehl's eye opening serum and thought it was a good product, you could probably pair it with the creamy avocado eye treatment. Most Kiehl's counters are pretty good at giving you samples too. Minimizing time in the sun, and getting a good sleep goes a long way too.
