I bought this after reading the great reviews, and seeing it featured in the WSJ. I've recently been having hormonal breakouts on my chin, and I've had stubborn clogged pores for a while (probably since I stopped using my previous clay mask, which didn't feel like it was working). I used this only once so far, and the results were immediate - the majority of the clogged pores were gone - I'm convinced that as I continue to use this, I will have no clogged pores left. The initial results were great, and the results the morning after were even better - my skin was more even and blemishes were smaller. Will continue buying for sure.
