As with all my reviews for anti-wrinkle products, I've never bought them, they were either free to try and/or free gift with purchase. This one was also a free gift. Now, this formula comes in tube format, has sort of a thicker, but almost sticky/tacky consistency, is a deep yellow color, and has sort of a coppery shiny residue affect after applying; but it's hardly noticeable if you blend it in properly. I did notice a difference in the appearance of my dark circles and puffiness under my eyes after just one week of use. You can even use this on your crow's feet as well. You need only to apply a little; it also helps that the nozzle ( if you can call it that) on the squeeze tube has a very fine opening on it, so a little does go a long way. Overall, I'd say it's worth a look into.
