This is the concealer I have been using: Glamoflauge by Hard Candy. I use very very little in three spots: on the sides of my nose (most of us have redness there) underneath my eyes and over any blemishes. I put little pin sized dots in these three places and blend them in with my finger. I put on concealer after I apply foundation. The reason I do this is because applying concealer before causes it to disappear as you blend your foundation. Wait for your foundation to set, then apply this for extra coverage in spots that have redness.
