Oh yeah, small addition. If you use the organic apple cider vinegar on your face dab a little bit under your chin first and leave for like 15 minutes to make sure it doesn't irritate your skin. I have no problem rubbing it full strength right onto my face but some are more sensitive. If you are sensitive try diluting it with water or just use plain water to mix the clay masks. You can also add a couple drops of tea tree oil to the clay mask...I sometimes do that too.
