This eye serum has a cult following so being a skin care junkie had to try. It is very sticky and you pat on so it is only for night use and for very dry skin. It comes out a beautiful bluish purple color, but goes on clear.. In the morning I woke up to less wrinkles and very moist skin in the eye area. You need the smallest amount for both eyes as if you over apply as I did it interferes with seeing,sort of like a film over eyes,but no irritation and so gentle. I think this will be a great serum to use in the dry cold weather before bed. Considering how little you use and how long it lasts and results well worth the money. You can also use excess on dry lips.Great gift idea for that hard to buy person.
