Firstly I don't work for any cosmetic company, I don't buy expensive products and I don't look after my skin, I have no beauty routine. I am 41 and I have open pores. Honestly I have seen a difference in my skin, my open pores seem to be cleaner and I've only been using this product a week, once a day. My skin is a little dry, hence why only using it once a day. When this runs out (and I can't see this happening for months) I will definitely buy it again, I am also considering buying other Dermalogica products. One very happy customer. Oh and it arrived very quickly (3-5 day delivery)
