I love using these! I usually use these at night after a stressful, long day and when I take them off, my under eye feels moisturized and hydrated. I have really dry under eyes so I am always looking for good masks to use and this one is amazing! The other morning I woke up after a very long night with friends, and my under eyes were so puffy. I used this in the morning for about 2 hours, and afterward, most of my puffiness was gone!
