I'm sure readers will think I'm exaggerating or work for the manufacturer, but this SKII product is a game-changer. After one bottle, I awoke to a face I hadn't seen in years. After two bottles, my 42 year old daughter arrived for a visit and said "Great, now I look like the mother!' It has dramatically refined my skin, fading dark spots, minimizing pores and relaxing expression lines. I hope they never stop producing this.
