I wrote a hub about makeup yesterday. Honestly, I believe it depends on what concealer you have. I have tried many of them and never found one that worked as good as bareMinerals bisque along with the concealer brush. I never knew that could make a difference but it does. It helps to conceal dark circles, dark spots, blemishes, and even uneven skin tone. I have seen other concealer brushes at the drug store so I believe it has a lot to do with the way the brush works giving you more of the concealer to apply to the area. I put a light coat of the bareMineral foundation on, then apply the concealer, then another light coat of the foundation.
