This is a relatively new product for Kiehl's, and I first tried it as a sample (then tried it again, as a sample - they're wonderfully generous with the samples at my local Kiehl's). As a Dr. Brandt's Microderm In A Jar devotee, I was interested to try a similar product from a line (Kiehl's) that agrees with my sensitive skin (I use the "blue" line cleanser, toner, and moisturizer, as well as the detergent-free cleanser). This is an awesome exfoliating product, gentle, in a very neutral base (not drying, but not too creamy where it could leave a residue behind). You can control the harshness of products like this by using less pressure or scrubbing for less time. I do love Dr. Brandt, but when I run out (he lasts a solid year and a half with regular use) I think I will purchase the Kiehl's - it's only $40 compared to the Dr's $75, and I really like that it comes in a squeeze tube so that you don't have to stick your paws into a jar to scoop (I use this in the shower much of the time, and open jars beg to get a big splash of water in - please don't dilute my crazy $75 scrub??) After I micro-derm, I chase my husband around telling him to feel my face because it's so soft & smooth!
