Robin's product list 101: "Pencils have more pigment and tend to go on a little darker and with more precision. Powders are a little more sheer. I like to use pencils for brows that are a little more architectural and defined, and I like to use powders for somebody that likes an extremely natural brow."
I, personally, love a coat of Benefit's Gimme Brow Volumizing Fiber Gel or Glossier's Boy Brow.
