1Add enough witch hazel to fuller's earth to make an easy-to-spread paste. Ad tincture of benzoin. Stir thoroughly. Before applying, open your pores by steaming your face with a cloth wrung out with hot water. Don't remove mask until it dries and hardens -- about 30-40 minutes. To remove, dip a cloth into water as hot as you can stand and apply over mask for a few seconds; use cloth to wipe off with a gentle rubbing motion. Rinse with warm water. Follow with cool water. P.S. Plan this mask for an hour when you take the phone off the hook (or shut cellphone off), and ignore the doorbell. Talking is impossible.
