This is a wash off mask that is beneficial for oily or acne prone skin. Charcoal also pulls out toxins and removes blackheads. Remove a small amount of product from jar and apply a very thin layer to clean dry skin (afflicted areas, not necessarily full face). Leave on for 15 to 20 minutes. Wash off with mild cleanser and water. You may need to wash 2-3 times. If later was too thick, use a makeup wipe to remove excess. Be sure to moisturize!
