My dermatologist is who suggested Revision to me a few years ago and it is amazing! I have tried a ton of other brands and Revision is the only one that works. I have very dry skin and the firming night treatment works wonders! Just a little bit goes a long way and I don't have to continuously apply an extra layer and hour or so later like other creams. I am also thankful I can order directly from the Revision site now since I am an hour away from my dermatologist I can't always run up to buy more.
