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!

Not a scrub.

This is an exfoliation not a scrub. They shouldn’t write scrub on the description because it’s not. It’s not what I wanted at all.

This actually works! Got rid of my numerous white and black heads. I use this as a facial cleanser 2 to 3xs a week to keep my skin glowing and my pores cleaned out!
