Aztec Secret Indian Healing Clay ($11) has a tried-and-true formula that has worked for countless people with acne-prone skin. The mask is made with 100 percent natural calcium bentonite, which is a green clay that's incredibly absorbent. More than 15,000 customers have reviewed the product, and 70 percent of users give it five stars. That's a pretty spectacular reputation.
I tried the mask myself and was very pleased with the results. When you open the jar, you will find a powdered clay that you mix with equal parts apple cider vinegar or water — it's up to you. Many customers claim that the vinegar will give you more effective results. You stir until you get a thick yet smooth paste that you can put on your face with your fingers or a brush. Allow the mask to dry. Here's the important part: if you have sensitive skin, only leave it on for five minutes. Any longer and you may experience irritation. If you have normal skin, you can leave it on for 15 to 20 minutes. As it dries, you will feel your skin tightening — that's a good thing. Wash it off with warm water once you're finished. You may look a little red after you take the mask off, but that should go away in 15 minutes or so.
I used the mask three times in one week, and I didn't get a single zit. My skin felt baby soft, and it was the clearest it had been in months. Many fans of the product claim that it has been a miracle worker for their severe acne.
