I got a very good sample of this from Clarins, in a glass bottle with a pump and it lasted for three weeks, so I was impressed even before I applied it. But that's where it ended, nothing happened to my skin, in fact it ended up looking worse because I stopped with my P.M. AHA/BHA routine to try this. Pretty soon I got some uninvited zits and blackheads and my skin's texture didn't change for better either. So I guess it's not for me.
