I have dry skin, so I am a big fan of good face serums, and i've tried quite a few. The ElevenSkin Rescue Omega 3 Serum is just about alright. What I liked about it is that the sample is a healthy size, and it comes in a format that is easy to carry around and store. However, even for my dry skin, it is a little too oily in texture, and leaves a sticky feeling, so it cannot be used during the day. There are other great serums that are more water-based out there, especially the ones that can be used during the day, that don't have this problem. And there are other great serums that are slightly heavy that are used at night, but then your skin feels transformed the very next morning. So I'm also still not quite sure what it is supposed to do because it just doesn't seem to have the desired impact either.
