This really is more than "just water." I am no fool when it comes to water-based primers and moisturizers, and have struggled for many years to find the right products that do not leave my skin oily or make me break out. I LOVED it the moment I tried it in my monthly Birchbox sample several months ago, and traveled with it all over Europe. The mist worked to lightly moisturize and reduce irritation on my face, and also worked as a very FINE primer for my foundation and eye-makeup. I revere this product SO much, that I've purchased after my sample ran out. I do not often write reviews, (as this is my first official Birchbox product review); However, I feel this product deserves the necessary praise in how well it has personally worked for me. This product is a must in my makeup and moisturizer toolbox!
