"I found these to moisturize my eyes very nicely. I have no bad reaction. There is no odor. They work well. My only complaint is once you break the tab and open the individual capsule it needs to be used all up. I realize these do not have preservatives and that is specifically why I bought them but I used another brand that allowed you to recap and use it up within a day or two. I prefer that Packaging. But these worked find."
