This soap has been a huge blessing to my family! I found this soap at a Native American Festival in 2007. I had already spent over $400 on treatments for my daughters acne (it was really bad), including pro-activ (which helped for a week then made it worse). The vendor confidently insisted that it would help her. I bought a bar...it is now 2022, the soap STILL works beautifully! I buy it & ship it to her in Japan. Myself & 2 other daughters also use it. I am 56 this month, no one believes me. My husband has seborrheic dermatitis...it works well on that as well as "backne". A few years ago, I shared the soap with my co-workers high school age children. They were the only ones in their peer group with beautiful, clear skin. She shared the soap with her sons baseball team...the soap is now officially legendary! Please try this soap before resorting to antibiotics to treat your acne. If you use it regularly, you will not be disappointed.
