My favorite part about modern skin care is its effectiveness. Good products deliver visible results within weeks or even days, and while they won't give you a face lift or a nose job, they make one's skin look as good as possible without having to use methods like the one you see above. Other than sun protection (and correcting past sun damage), my main focus is keeping my skin looking alive. It's all quite Harry Potter-like: Potions, Defence Against The Dark Arts and a touch of Herbology, so I like that Kanebo Sensai's nearly magical serum is called an "Essence".
Cellular Performance Hydrachange Essence looks like a runny lotion but you can tell as soon as you apply it that there's some heavy duty concentrated moisturizing there. The "magic" is in the contrast between the lightness of the texture (and the absolute lack of any grease) and the instant plumping and suppleness it gives the face. And these results don't vanish. My skin remains happy for long hours, and I can also tell now, after over a month of daily use, that I've achieved a new and better balance.
Granted, the real test of a superpower hydrating product is during the winter, when freezing temperatures and overheated spaces conspire to age us all, but from what I'm seeing now I have high hopes for the Sensai Hydrachange Essence (and also for the cream from this series which I will start testing as soon as the weather changes). As for integrating this product into my existing routine, I use it every morning after moisturizing and once again in the afternoon or evening once I've taken off my makeup. I still use the brightening Cle de Peau serum right before bed and the results are great, so there's no conflict between the two products.
Bottom Line: Fabulous.
