I LOVE this stuff. It has helped so much with pesky blackheads. I used it for a few days in a row and now I just use it maybe 1-2 times a week. The smell isn’t great (it just smells like washed rice) but I do it before I shower so the smell doesn’t linger. Great product and I’ve already shared with two others who have also purchased it and loved it!
