I was a bit confused as to the purpose of this product, as a standalone I'm not sure if one can use it as a cleanser, exfoliator or moisturiser (the claims on the instructions seem to indicate all three)?... But this is infact meant to be used in conjunction with another product, the Sebu-Lac Oil which I assume is meant to be used as a type of treatment on the skin? The neccesity of using them together can put this steps price point a little high and dealing with both the bottels simultaneously can feel a bit clumsy. All in all, I didn't find the role of this step in the range all that clear, although I can appreciate the neccessity for the use of a chemical exfoliant in a skin regime. This product contains lactic acids to reduce signs of skin inflammation, I just personally feel that the mask in this range is better suited to that.
