Have I told you I love this stuff? Don't mind the broccoli, I was fitting in this facial during my work lunch break :) I usually leave it on for approximately 20 minutes. I mix just a little spoonful of the Aztec Clay with another 1 1/2 spoonfuls of Apple Vinegar and then use a foundation brush to mix + smooth onto my skin. I leave it on for about 20 minutes. Don't worry afterwards if your face is a little red, that means it worked! Let me know how it worked for you. I bought my Aztec Clay from my local Nature's Own but you can purchase it online too. The product lasts FOREVER so it should be a staple in your beauty closet for you.
PS-I was having my lunch break at my house + making this mask. MULTITASKING TO THE RESCUE!
