I use a bronzer by NYC, applying it over my liquid foundation (L'Oreal's True Match Super-Blendable SPF 17).

The foundation gives me great coverage and with the bronzer over it, a beautiful finish. However, by the end of the day, or even after 5-6 hours, the bronzer looks bad - with streaks, patches, and an unsmooth finish. My foundation starts to show in random spots and the makeup overall looks dried out. The bronzer looks really splotchy.

Would using a good finishing powder or primer over my liquid foundation (before applying the bronzer) be the answer? If so, can anyone recommend one?
