Review (3/5): Meh.
This is an interesting concept, but I honestly saw no results. In fact, they made my eyes tear up a bit, which left them smaller than usual. These are swoosh-shaped, gel-like patches that stick to your skin, with no adhesives. You are instructed to lie flat while they are on, so although they would likely stay afixed, you really can't do much moving once they are on. For under eye dark circles, the effect was zero. Nonetheless, it is nice to give yourself a reason to lie down for a 20 minute break, and the pads are cool.
