I've been using the Daily Microfoliant by Dermalogica for a while now. All in sample packages. I use it once a day at night time to get the grime of the day off. I put about 2 quarter sizes in my palm and rub slightly with water before apply to my face.
The product is a white power that you mix with a bit of water. If you mix too much water you won't get the scrubbing exfoliation on your face.
It leave me fresh faced and just clean before bedtime. Sometimes I'll spray their toner on after but usually just a night time moisturize and to dream land I go.
