This is a good quality powder, one that I can (and will continue to) use alone, or over just a concealer, at least in the hot weather.  I can't really comment on how well this works to set foundation because I have not yet mastered the art of using this on top of Dermablend foundation.  Part of the problem is that there is no single shade of the foundation that is a good match for my skin color and tone.  (I have to blend and mix three (3!) shades of the foundation to get something that approximately matches my complexion.)  Since it's too hot to wear anything but the lightest makeup I am not really motivated to keep fooling with the foundation. This powder is a good solution, one that is better than the mineral powder I had been using.
