The eye patches claim to soothe puffy eyes, leave skin hydrated, and provide a cooling sensation. The patches seem to help decrease my under eyebags when I don’t get enough sleep the night before. I’m not sure how much additional hydration it adds to my undereyes though. They are cooling and a soothing step in my skincare routine. They would probably be even more soothing if you store them in the fridge. I use these while lying down since they tend to slowly slide down my face.
