This eyepatch has a cooling sensation when applied, very soothing when my eyes are tired and dry. The soothing really works on my eyes, to brighten it may take time. A good combination of matcha + probiotics, which can strengthen the skin barrier around the eyes to become firm. The patch fits on my eyes and little bit slippery, make sure you use this on lay down. A tip from me, keep it in the refrigerator so that it is fresher and cooler when applied. Bye Bye Puffy Eyes!!
