To cover dark circles, I apply a little peach toned colour corrector to my under eye, then blend out either with the warmth of my fingers or with a small concealer brush. next I apply a little concealer to the inner and outer corner and allow it to dry down for a couple of mins to achieve maximum coverage. Next, I blend out with a concealer brush and then go over the area with a slightly damp beauty blender to remove any creases, before settiing the under eye area with some translucent powder using a powder puff.
