Difficult to stay on
Size: 1 Count (Pack of 6)
Won't stay on your face. Only a few patches come in the box for a few days. Price sounds good until you realize the quantity isn't much. I did not notice any difference.

I love these patches, have been my favorite go to since they came out. I think they do better than any other patch, spray, or gel I have used so far.

It works!
Size: 1 Count (Pack of 6)
Got this for my husband and it really works. He left it on while he was drinking his morning coffee. He's 1/2 Asian and has normal puffy eyes from dusk to dawn. It's just been been one day but the results were truly amazing. Puffiness 75% go e in one eye and 50% in the other. Im impressed.
