SkinCeuticals Micro-Exfoliating Scrub, $30
Exfoliates with: diatomaceous earth

SkinCeutical's facial scrub contains microbeads made not from plastic but from diatomaceous earth, a (tongue-twisting) mineral that's so natural you can actually eat it. (And kill bugs with it, but that's beside the point.) Designed to buff away dark spots on mature, non-sensitive skin, the scrub is made with aloe vera to moisturize and calm skin.
