I bought some of this soap off ebay, can't remember the name of the seller but I'll check my ebay account if anyone's interested.
I got it about 2 and a half years ago, when I was in my mad "got to try every soap on the planet" stage.
From memory, it had quite a funny smell. But I will say this, I had a huge blackhead (I know, gross) under my nose that I had so much difficulty getting to. I'd tried all sorts of implements to squeeze it out, those pore strips, face masks, everything. It wouldn't budge. Coincidence, or not, after using that soap ONCE it came right out. Now it may have done that all by itself, it's time may have been up, who knows.
I'd be interested in it as an additive also though, just to compare. From memory, isn't it some form of cactus or something?
