I actually use either just water, or an oat sock. I fill an odd sock with oats and use that as soap. Much nicer, better for the planet, better for my wallet, better for my skin, all round better. If you haven't tried an oat sock facewash you really much! It's cheaper than an egg too.
I swear I sometimes I feel like I have been sheltered under a rock. Then on the other hand . . . well, there is just too much erky perky stuff in the world to know it all, which is a great mercy. Please don't look it up - it involved a traffic cone.
