How do you make your own face scrub?

Here is a very easy recipe for an efficient body scrub: take some coarse polenta (medium grade) and mix it with some clay (green or white). Quantities vary on the surface to exfoliate, for the face, 1 teaspoon of clay for 1/4 teaspoon of polenta.

Mix with a bit of lukewarm water to have a paste and scrub. Rinse with warm water, it feels fantastic.
