Clay comes from the ground, making it rich in minerals. The minerals found in clay, along with its ability to absorb toxins and exfoliate the skin, makes clay an excellent skincare ingredient. There are a variety of clay options available. For simplicity sake, I stick with just two clay varieties for the DIY recipes here at Live Simply: kaolin clay and bentonite clay. Use clay to make DIY dry shampoo, a detoxifying face mask, foundation powder, or an anti-itch cream.
