I've been sampling different kinds of serums, and thought I would give Lise Watier's version a try. It comes in a unique container with one side for day and one for night. The first thing I noticed was the scent - it wasn't unpleasant but was a bit stronger than I would like. (sidebar: what's with strongly scented facial products???) The serum went on easily enough (both sides) but seemed to leave a bit of a tacky feel to my face. For the night version that isn't an issue, but I wouldn't want to have my face feeling like that in the morning when I then want to apply other product and makeup. After using this for a couple of weeks, both morning and night, my skin felt soft...but I didn't see any noticeable difference. I don't think that it's worth the $80 price.
