I've had this product sitting at the bottom of my drawer for years and only recently did I start using it again, only to remember why I had stopped. I had wanted something that would eliminate or at least help alleviate my dark undereye circles and sometimes puffy eyes. I had bought this product simply because it promised to do just that. Its claim is that it will instantly reduce the appearance of dark circles and give the eye area a cooling effect. I agree that it does instantly feel very cool on the skin and soothes tired eyes, much like if you would place cucumbers over them. The tube reminds me of a lipstick which rolls the product up as you use it. It comes with an additional plastic cap to keep it airtight. I havn't tried to remove the cap when it's not in use, in fear that it might dry out. Although you don't need to apply much product to the eye area, there isn't a good amount of product in the tube itself compared to the packaging. This is a little disappointing considering that I did pay close to $10 for it. As I was saying, I do enjoy the cooling effect, but I never saw a difference in dark circles or puffiness. It did make the area a touch brighter, but not enough to say that it made it look better. I still needed to apply concealer afterwards. In addition, when applied outside of the delicate undereye area, the product did tend to clump and show up looking white on the skin (i.e., it dried clear under the eye). Therefore, you have to double check in the mirror after a few minutes, in order to make sure you're not waking around with gunk on your face. I don't think this is worth the price it is sold for. I might as well just put cucumbers over my eyes, since it will give me the same, if not a better result.
