I really do love The Concentrate for making skin feel so buttery/helping with recovery. My skin was a bit rough following a recent mountain hiking trip (alpine tundra-induced peeling), and the concentrate had my skin back in shape within essentially a day. It is expensive but worth it for when you need it (and a nice treat for when you don't).
I've been a La Mer customer for years now ... but am truly impressed with The Concentrate. I recently had lunch with a very old friend that I hadn't seen in quite a while ... who actually asked if I'd had a face lift! How amazing is that? I will continue with my daily regime forever!!!
