Using makeup brushes to apply your makeup, is not the only way to do it. Not only that, but your fingers might just do a better job at times. So forget the brushes for once, and try something else!
Using your fingers will ensure that you get a softer, smoother look, and that everything is well blended and polished.
Blend foundation outward, using your middle and ring fingers to create a seamless effect. Press on lipstick with your middle finger for a long-lasting stain. Dot a little bit of gloss in the middle of your bottom lip- which will give you sexy, full lips.
Use your ring finger to apply a sheer wash of eye shadow. Pinkie dab a pearl hue in the inner corners to brighten up your eyes.
