Apply Face Mask Clearing to cleansed skin. Avoid the lips, the skin around the eyes and very thin or irritated skin. The mask dries after a few minutes. Leave on for 5-10 minutes. It may also stay on overnight. Rinse off with warm water and follow up with a Freshener according to your skintype. Use Face Mask Clearing once per week on normal to dry skin, 1-7 times per week on oily skin. Preferably, apply it after AHA & Jojoba Peeling. The skin will absorb the mask’s active ingredients more effectively when it is newly exfoliated. Daily acne treatment: Face Mask Clearing is excellent to use on spots, though it may sting slightly. When needed, the mask can be applied onto specific problem areas, multiple times per day. This daily treatment can be performed for a maximum of two weeks on end.
