I like this product so far. You can feel it working on your eyes as it tightens and firms them up. There was no stinging and didn't make my eyes water. Which most products do. I was really amazed by just one-time use. I took pictures and my right side has product. which has my eyebrow ring. And the other side has no product. This is with one-time use. Maybe there is a little difference. It looks like it to me. Hopefully, with everyday use my dark circles will improve. And my eyes and cheek area will lift up.
