Is this a wash off mask or a peel that pulls out impurities/blackheads?

I use the Aztec clay mask and it helps a lot.

Well charcoal is supposed to help with black heads also I agree with the other person on here who said to use aztecian clay and Apple cider vinegar that stuff is the bomb

Try Aztec Healing Clay Mask and mix it with apple cider vinegar. It definitely helps to draw out impurities in the skin.
