This is the first emulsion that I have ever purchased, so I don't have much to compare it to. I don't have much to say about this emulsion. It's not bad, but I don't think that it's that good either. When I first used this emulsion, I felt like it had a slightly sticky finish, however, that may be from the combination of my toner and emulsion reacting to each other?? I'm not sure. I don't notice the sticky finish now though (I have been using it for several months). Also, this emulsion has a thicker consistency than other emulsions (my friend told me). My skin is still able to absorb it pretty well though. I don't know if the collagen in the emulsion had much effect on my skin, but that is probably because I'm still young, so evidence of aging isn't really showing on my skin.
