Promising review: "Saw this in a BuzzFeed article and was intrigued. The blurb was interesting, and the reviews were correct: this helps my tired eyes with just a swipe under each eye. My puffy eyes aren't so puffy, and my face feels less tense. I keep it in the refrigerator, too, which adds to the cooling effect. I also swipe it over my eyelids, which relaxed me before bed. Will definitely purchase again." —S. B.
