Im in love with these under eye patches. These are not your regular under eye patches. My eyes look refreshed and hydrated. I often keep them on all day and i love the tightening effect after they dry down. My under eye feels firmer and looks plumper. Sometimes i will even wear them overnight. They are very cooling. I love that they are clear so not very visible on zoom meetings. For all that it does, it is definitely worth the hype and the price.
