Promising review: "I have had acne for nine years. It's cystic acne mainly, and sits on my cheeks and chin primarily. They are deep, red, and take weeks to go away (if they ever do). I have tried switching my laundry soap, multiple face washes, moisturizers, natural oils (like coconut), my makeup, and many spot treatments. I saw some friends on Facebook talking about this soap, and I figured, 'What do I have to lose? I've tried everything.' So far, I have been using this soap for exactly one month. Immediately, I noticed the redness decreased. Over several days, I noticed I had no new pimples developing. After the first two weeks or so the majority of my acne was gone. Now, after one month, a lot of my dark scar spots are gone or seriously diminished. I have only a few remaining red spots. I have made NO other changes to my diet, makeup, or skin routine. I have only been using the soap two times a day, morning or evening." —TammyLou
