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 have 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 did not actually notice anything visibly different these might be worth it if you are simply looking to make your eye area feel better
