Collagen Under Eye Patches, 24 Pairs

These kind of work. They do seem to lighten the dark circles under the eyes. The reduction of the puffiness is not as pronounced. I don't understand this delivery mechanism. If the active ingredients are good for reducing the dark circles and puffiness, why not put them in a cream that can be applied. That way, it will stay on the skin for much longer. The most useful time to use these is in the morning, getting ready for work. It is hard to reduce your activity level at the time you are trying to get ready to go out. They do tend to slide down a bit, but that part is manageable, as long as you are careful what you are doing. They do smell good!
