Sarafina's Green Tea Eye Gel - it has really really helped my dark circles (bad - the hereditary kind), plus puffiness and fine lines. And given that you can get five Sarafina samples for 4$ (Bill makes no bad products, trust me), and my sample lasted for a month, that's not too shabby. My full size is one ounce and cost 17$ US, and will last a really long time - you only need about half a pump to do both eyes.
