Finally I have found a product that works on my skin! I have had a struggle with large pores and oily skin for such a long time. I noticed a difference in my skin the first week of using this. I use it twice a day and appreciate the strong, yet gentle, ingredients. I started out with the smaller size, but I know I will be purchasing the larger one when this runs out. Thing is, that will be a while, as you need such a tiny amount.
