This stuff is awesome. I used to do the acne.org regimen but it always left my face really dry, itchy, red, etc., and it took a long time. And without any acne regimen, I usually have about 6-12 ugly and painful cysts on my face at any given time. I switched over to the Coral KAVI bars (with the SA 8 for spot treatment) and I was honestly blown away. It was SO MUCH faster and easier, and my skin felt comfortable and balanced all day, and there was a serious reduction in my acne (compared to either the acne.org regimen or just washing my face). The Coral KAVI bar is also a lot cheaper than many other 'serious' acne treatments. About six dollars a bar, and each bar seems to last forever. I started using Coral KAVI six weeks ago and the first bar doesn't seem to have gotten any smaller!

Advantages: Fast, easy, effective, inexpensive.

Disadvantages: In the evenings (I shower in the morning), the solid bar is a little less convenient than a liquid cleanser would be. Not by much, though.
