Specialty Facial Bar
 
This soap, while specially formulated for the face, is great all over. It's clearly a black bar and is loaded with clays and activated charcoal. I didn't skimp at all and so this bar can produce grey bubbles and may temporarily discolor a washcloth - until it is rinsed or washed. I use this bar myself and it has never, ever stained or ruined anything.
 
This bar can be used all over, but if you choose to use it for the face, I'd suggest that you try something different. To use, dampen your face, but not the bar. In circular motions, rub the dry bar on your wet face to make a concentrated paste. Allow it to dry for a couple minutes, then use a washcloth to wipe and rinse.
 
Allow the bar to dry between uses to extend the length of the bar. Also, I cut this one in half. A single bar can last for months if used as above.
