Use foundation brush or just fingers?

You may know that the best way to apply liquid foundation is with a foundation brush, sponges absorb your foundation (which wastes it), and they also have bacteria,your fingers will work but they tend to just spread the foundation around your face, and provide a less even application. The foundation brush will make your foundation last about three months longer,and they can be washed once or twice a week in luke warm water with your facial cleanser (no bacteria). Try this test out: take a mirror and put a few drops of foundation on it,spread it out like you would on your face, then with your fingers,now do the same thing with the foundation brush, the makeup goes a lot farther alot more evenly.Just remember when using a brush you need a lot less makeup, too much will produce brush marks on your face!
