One of those long-standing, not expensive but effective products. If you want a clay mask without junk in it, this is great. Mix it with cider vinegar. It fizzes a bit (due to the alkaline pH) and then spread it on with a foundation brush. Let dry. It does everything a mask should do, but not expensive or with fillers. You can also use it as a blemish healer: apply the clay with vinegar and let it dry over a bump (not an open one.) You can also use it as a hair mask.
The Aztec Clay Mask basically acts like a vacuum for your pores in the 5-20 minutes it’s on. The 100% natural calcium bentonite clay draws out all the impurities deep in your skin for what has been called ‘the world’s most powerful facial’. I can’t say it’s “the world’s most” anything, but it is the first thing I have ever used that wasn’t prescribed by a dermatologist and actually works. In fact, it’s the first topical treatment I’ve ever used (prescribed or not) that has actually worked.
