I use an oil-free camoflouge by glominerals. When I'm doing an application I spot it over problem areas first, then proceed to the base and everything else. After everthing else is done, use the camofluouge again or a concealer and spot and blend into other makeup. In my experience thus far it never fails. A blending sponge works good to blend. Also I'm a firm believer in gold or yellow undertones for all skin colors, just finding the right hue is the key.
