I have been using eye creams for years and at 47 years old I have no crows feet or lines around my eyes. I was eager to try Serious Skin Care Glucosamine Refining eye cream because the other Glucosamine products are so wonderful. The Glucosamine eye cream feels so smooth and silky and goes on very easily around the eyes. It is very emollient yet it sinks right in. I like to use it at night because in the morning after sleeping with it all night, the skin around my eyes look very rested and feel so soft. I have also used this in the morning underneath my makeup and since it sinks right in, my makeup goes right over it with no problem. It looks and feels great with the makeup on top of it. This eye cream is one of the best and my eyes are the proof that it works.
