I bought this cream especially for the neck, which I hated as much as two wrinkles, but it took 6 weeks, and the wrinkles on the spot. But when used under the eyes overnight effectiveness was evident almost immediately: in the morning dark circles lighter and smaller (I emphasize - shallow, deep I do not have, about them I can not say) wrinkle is gone. The cream is very cost effective, especially when used only under the eyes: I just touch it with your finger, and it is melting from the heat, like oil, this layer is enough for the eyes, but on the neck, of course, need more. The cream is thick, beige and yellow, with a slight sour smell.
