For 1 minute, scrub your lips with a toothbrush in tiny, circular strokes. The washing will increase blood flow to your lips, making them seem larger and pinker. It will also remove any flakes and improve the reflectivity of your lips, giving the illusion of plumper lips. After one minute, rinse your mouth out with water to remove the scrubbing effect. Your lips will appear fuller and pinker than ever before.
