Determined by my wife. A product to be applied in two stages: the first is based sheathing effect, sensible volume to lashes. Then, in the second step of applying mascara itself. So makeup eyelashes slightly longer time than usual for a result, say, somewhat short of the advertised great effects. I, for one, the thin eyelashes. The effect sheathing actually gives them more volume but it's far from most revolutionary BE compared to a conventional mascara, I have not found them particularly "super stretched" or "super black", such as the ad claims. A good point to note: Despite two layers, it removes makeup very well, both with quavec milk lotion. Mixed results on me, but probably best on eyelashes already provided.
