The above picture describes what each makeup brush is used for. It’s best to use brushes when applying your makeup and not your hands. Your skin on your face is very fragile. When your pulling and tugging on the skin on your face you tend to create premature wrinkles and cause your skin to fall a lot faster than it should. The brushes are a lot easier on your skin and give your makeup a different finish that if you were to apply with your hands.
