In Touch reported that Halle Berry used coffee grinds as a body scrub when she ran out of her exfoliator. Catherine Zeta Jones uses strawberry seeds as a skin brightener and exfoliator (she claims it even whitens her teeth) and Christie Brinkley admitted to using kitty litter in a pinch since the main ingredient is clay.
Pretty resourceful ladies, don't you think? I remember when Bobbi Brown came out with Sandbar soap as part of the summer Beach collection and I thought that was really clever and inventive. Tell me, what is the wackiest ingredient you've ever had to use in place of an exfoliator?
