Promising review: "Definitely works! The actual soap lasts a long time and lathers really well. Helps keep my skin clear and reduces my red acne scars. This is my holy grail when it comes to face soaps, and I tell all of my friends and family about it. I've gone through three bars of the blue clay soap but after going through a bar of this charcoal one, I think I slightly like this one better. Although they're both amazing at keeping my acne under control and my skin clear, I feel like personally for my skin, this one works a little better at fading my red acne scars and helping my overall skin texture." —Marylin K.
