This eye serum comes in a .5 oz pump, is sealed closed and wrapped nicely. It is so awesome for puffy eyes and dark circles, even helps with bags and wrinkles. This eye serum is a natural way to reduce the puffy dark circles that comes with age. It feels great going on, dries very fast and feels good for a long time. I use it twice daily, once in the moring and once at night. This is light the fountain of youth but in a bottle, I really like it.
