I don't know if I'm ever going to be able to do without this mask. Let's start with the marshmallow reference -- it feels fluffy, it looks white and it smells sweet. Totally yummy. So easy to apply, not too thin a consistency and not too thick / hard. I sometimes just apply to nose and chin or big zits and leave on for longer. But other times I apply a thin layer all over face and let sit a shorter amount of time. It sounds crazy... but I sometimes even use this a a cleanser. Basically, I splash my face with water to make sure no products are on it, rub this in my damp skin, and go do other stuff. It soaks up the bad, leaves the good, and has a terrific manual exfoliation when you're washing it off with warm water. Afterwards, my skin is as smooth as a baby's bottom and so bright. Love it in the morning before VitC or at night before retinol. Small enough to travel with. Not at all embarrassed that I hoard this!
