I use it in the morning with the lotion but I use to use it morning and night and if never over dried out my skin. Now I use the cleanser with my clarisonic brush and then the lotion in the morning and then the seaweed wash toner and lotion at night. I also use the seaweed claps mask twice a week at nigh followed by the Glamglow Thirstymud.
I've used the cleanser for over ten years. I must say that it provides a wonderful clean, but do NOT use all of the tea tree products together, or you'll be dried out and inevitably greasier than you started!
