On lazy or rushed days when I don't have enough time to apply BB cream, I would sweep this over my face for coverage. I'd say that two strokes from the pot is enough for my whole face because I like to keep my look very natural.
The nice thing about this powder is that it's so easy to build up to the amount of coverage you want without any caking.
It provides a matte finish so I like to give my face a final spritz with Fix + or MAC's charged water so that it looks more dewy than dry.
