I love this! It feels great under your eyes and it smells very good. I love the packaging! The scent reminds me of cucumber melon. The cooling feeling only lasts for a couple of seconds while u are applying it and after. I use it in the morning after applying my face lotion and pat it in gently. My skin feels slightly tighter and moisturized after patting it in. It helps me feel more awake in the morning but I am not sure if my eyes are less puffy. I don't think it helps much at all with under-eye puffiness or dark circles but it does contain haloxyl (according to their website) and that is supposed to be a whitening ingredient. I don't really use this throughout the day because I usually wear undereye concealer because of my chronic dark circles/puffiness. I tried using it over my concealer by patting it lightly but this took off some of the concealer so I just use it before applying make up only.

PHOTOS: The first one (blue-ish colored one) is the so cool eye stick and the white colored one is the whitening base stick. As you can see, it is a small stick and about the size of lipstick. I just posted the photo next to the bunny mist as a size comparison.
