We had some time ago already pins in which - similar to a deodorant stick - a substance was applied to distribute any dark circles or fatigue. That was quite nice, the first cooling effect was pleasant, but nothing more. The roll-on Nivea is similar. The small vial has a metal ball over which a kind of gel is applied. The cooling effect is surprisingly large and comfortable. At first glance, one can see that something is happening, which I rather have the impression that the wrinkles increase (skin shrinks?) Than less are ... The gel is absorbed quite rapidly (if you Rollert not too much) and then it was the same with the cooling. So far we have not yet seen that the area of skin had changed positively. A pimple points rather to an oversaturation of skin.
In short, as a gimmick and in between quite well suited to give the eyes a "freshness kick" without dip his face into the cold water, but not very interesting price. For people with really dry skin around the eyes but it could be a useful complement to other toiletries.
