Unbelievably good! I used this last night and it made my very sensitive skin quite red. However I need a cleanser to deal with my clogged pores and was reassured by the beneficial skin barrier ingredients. I also followed it with a soothing toner and lots of ceramides. Woke up and the redness is gone, and my clogged pores are visibly faded. Overnight! No new little breakouts, either. Highly recommend!
