It is the only product I have seen so far that makes a difference in the bags under my eyes that I have had permanently for years. It does a very good job, the bags almost disappear and the eye brightens. Of course, my bags come back the next day - I haven't used it intensively/everyday. However, it needs to stay on for a longer time (I leave it for 40 minutes) than what it states to do the job

I didn't see any difference in the area under my eyes. I just felt it cooler while wearing the patches.

I bought 2 boxes as I wanted to do a 2-week application to observe the result. The reason I bought them was for the treatment of my dark circles. (I kept them in the refrigerator to keep them cold) In the end, I didn't finish the second box as I didn't notice any difference in my dark circles. I would only recommend it for application on tired and swollen eyes as it creates a relative coolness and relief. For dark circles, I found that I had much better results using an eye cream instead.

For the money you give, it has results. It relieves the area under the eyes as long as you leave it on for more time than it says... I leave it on for 60 minutes and I actually see results. I have already bought it 3 times
