Used the Life brand peel off charcoal face mask, was gentler and not as painful to peel off but the trade off was it didn't work as well as the glue based masks.

I bought a small tube of black charcoal peel off mask from ebay for a couple bucks. This stuff is pretty great. It is hard to get it to wash off your hands, and makes a bit of a mess, but it really just remove black heads. Just do not put it over your eyebrows, it will rip them out!
