Here's something where a little goes a long way.  The foundation comes with a spatula and directions were to warm it up by mixing on the back of my hand before using.  It does a good job of concealing--the best concealer I've ever used.  Just blot, blot, blot.  I had a bear of a time washing it off my hands, though.  It is water and soap proof.  I was able to remove it off my face with makeup remover.
