Walnut Shell Flour is a coarse powder made from finely ground Walnut shells. It can be used as an all natural body scrub to deep-clean, renew and detoxify all skin types. Walnut shells are a gentle yet effective way to smooth and refresh dry calloused skin and are ideal for making body and foot scrubs, and soaps.
I am experimenting with this in facial exfoliant bars, I don't use too much as it is a little more coarse than pumice powder. It looks lovey in a bar, giving lovely natural colour and texture.
