I really love TULA products so I was very excited to give this eye serum a shot. First, I have to note how much I adore the applicator tip. It's slanted, metal-like tip offers a cooling effect on contact. The pump action insures just the right amount of product is distributed. Finally, the serum itself is hydrating and plumping. I immediately notice my puffiness and dark circles disappear. As far as any wrinkle or fine line reduction, I haven't been using it long enough to make a solid decision (hence, the four stars), but if it's immediate indications are any representation of longterm results, I am going to be very pleased.
