Review title is Comfortable cooling sensation [SEP] I was looking for something to help with my dark undereye patches and to generally revive my eyes. I have used these twice now around the holidays when I've been worn out. These comma-shaped masks are easy enough to apply - there is a little spatula thing to help lift them out in order to be sanitary. They have a wet, silicone-like feel that is very similar to the feel of a contact lens, only thicker. I found that they stuck to my skin fairly well, even when I was moving around. The mask felt nice on and was a bit cooling after awhile. The area under my eyes felt refreshed after using these, although I didn't actually notice anything visibly different. These might be worth it if you are simply looking to make your eye area feel better.
