makeup brush animation. Text: Beauty School - Lip Brush - A thin brush, with a pencil-like wand, that has soft bristles forming a tapered point. It's used to apply lipstick with more control to create a precise line and sharper definition. Another advantage of applying your lipstick via brush? It gives a more pigmented finish that helps keep the color on a little longer, too. To apply, dip the brush in your color of choice and then start blending from the center of your lips out toward your lipline.
