I absolutely swear by this stuff! I have just started seeing fine lines around my eyes, so I thought I'd give this a shot. It's an odd serum, not greasy or particularly moisturizing, but it sinks in. I use it mainly at night, because it does leave a little film which may interfere with concealer. I noticed the lines disappearing after the first week. I have been using it over a month now, and the outer corners of my eyes which were previously down are now noticeably uplifted! It's nothing short of amazing. The pump bottle almost dispenses too much, you really need only half-a-pump, but that's my only complaint. I will continue to repurchase!
