if so, what brands are best?
Sure, In a pinch most any bath product will work.
They make up so much thick and creamy lather with one of those shower poofy things that you probably COULD shave with it.
I find the key is to rub up a lather with as little water as possible on my hands then spread it on my face, otherwise it bubbles up too much.
I agree with everyone else - you could, but why?
Although, if you are going to try might I suggest this?
I use Pre de Provence soaps in the shower (French triple-milled cold press veggie soaps), and they are awesome on a lot of fronts - luxurious, wonderful scents, very moisturizing, slick, etc...I'd often though of trying it, lol.

So, you shower with a shield of poofiness?
