I consider myself to be a skincare junkie. I'm always on the lookout for new products that will improve my complexion. That's why I was totally shocked that I had never tested out this Aztec Secret Indian Healing Clay Mask ($5). It's 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 13,000 customers have reviewed the product and 71 percent of users give it five stars. That's a pretty spectacular reputation.
