Best Answer: As stated in the instructions this mask is to be used once a week, twice if needed. You apply it generously, leave it on for about 10 min. or so then just wipe it off (I use a cotton swab). This will still leave some mask on your skin and you sleep with the residue on. Then in the morning you wash your face as normal. Obviously, you can't follow your normal skin-care regime on the nights you use this mask. No serums, moisturizer, etc.
