I have been saving these for a time when I could really enjoy the experience, and his was I. I have been quite third lastly, and the change in temperature has been tough on my skin. These patches really make your under eye area feel cool, hydrate, and look healthy. I left them on for half an hour..only challenge is I couldn't put my glasses on, so I listened to TV for a while. It was clear that a lot of moisturizer had absorbed, so I feel great about giving some extra live to this area.
