I regularly use La Prairie products, and I decided to give this cream a try. After a particularly grueling week at work, my skin had become quite uneven and tired looking. I also had dry patches, which were only partially resolved by my daytime moisturizer. I applied this cream before bed and woke up the next morning with hydrated and even skin. I found it to be as effective as La Prairie's sleep mask, if not a little more hydrating. This cream can be used nightly, and works especially well when alternated with the sleep mask (which should only be used once a week). I also use the La Prairie caviar moisturizer during the day; the combination of these products has really made my skin look great.
