Works Super well for darkness and puffiness! Also, does not make my eyeliner or mascara smear/bleed. Great ingredients are also very, very, important to me!!! I have paid more than twice as much for less effectiveness. I also can be sensitive around my eyes. Not with this. I have also added the Blue Copper 5 Serum, for lines and dryness! It makes your eye area so smooth and firm!! I am so very happy with this and the other Osmotics products that I use. They are perfect for me and hopefully for you also!!
