How’s this for multitasking? The best way to keep your lips soft and supple is to brush them every time youbrush your teeth. After you’re done cleaning your chompers, rinse your toothbrush to ensure it’s free of toothpaste, which can be dehydrating, then use the bristles to gently abrade your top and bottom lips. Do this twice a day everyday and you’ll notice your lipstick and gloss applies much more evenly.
