I received a sample of this as a GWP from Nordstrom's and just loved it. I noticed my skin instantly looked brighter and did not irritate my skin at all. I was so impressed with this that I went to the Clinage counter to purchase the full size of this (8 oz. for $24.00) and check out the other items in this simple line. Cleanser contains 7.5% glycolic acid. Gently massage in and then leave on the skin for a minute before rinsing. As I am starting to do AHA/BHA peels this is very helpful in removing the dry flakies on my skin in the am.
