I use nars concealer (stick) or a MAC foundation (stick) in a slightly lighter shade to cover up the under eye circles. I use my finger and/or concealer brush
well i use the one from bobbi brown. this ones includes a loose powder. u can apply it with a brush oder jus wid the fingers n fix it then wid the powder. its really gud.
another one which like is from annayeke or from yves saint laurent - touche eclat. thats really wonderful
