I have searched for concealers and I am in love with Urban Decays Naked Skin line. I use a light shade to conceal and brighten up under my eyes, and a darker tone as a liquid contour. It is super light weight and full coverage. The shimmering powder seen above is used as a highlighter. This gives such a great coloring and tone. I recommend going into Ulta and trying on different shades to find your best match. You do not want to get too light or dark or else it is going to look un natural. Using a concealer as a liquid contour is not as forgiving as a powder. Color placement is very important.
