I got the deluxe sample of the above product from Neiman Marcus with purchasing Multi Active White water.
It is the most effective product from all the Euoko products I have bought so far. It is a rather thick cream that needs to be massaged in the eye area. It may tingle a bit. The cream smoothed the eye contour appearance and minimized under-eye darkness and deeper lines. The price ( 300 USD for 15 ml) is steep. It would be fair to assume that there are less expensive, but equally effective versions on the market.
