First, just to be clear, I do not sell, so I make soaps designed for my comfort or specifically for family with particular needs/desires.
I do have some specialty soap I would never use on my face if I were to use any soap on my face, which I don't:
Blacksmith soap for my brother, the blacksmith. It contains Pumice and Borax, which gets the stains of blacksmithing off his hands & fingers quickly as opposed to having to wash his hands repeatedly for several days before the stains came out of his hands using commercial brands. The blacksmiths in my family (there are two) and mechanics, use this as a hand soap only.
Anything with exfoliants (pumice, walnut shells, even dried tea leaves, etc.) I will only use on my feet, not even on my hands usually, because the bottoms of my feet are quite calloused, but my hands and face and the rest of my body are not. So even when I give these soaps to family, I recommend them as foot soap only. Exfoliant soaps may work fine for others, but because my skin is so sensative to them, I don't make them very often anymore.
I do not specifically make face soap because I do not use soap on my face.
