Lips can lose volume and become thinner over time. But did you know your lips can lose their color, too? The skin on your lips is very thin and delicate, making the underlying blood vessels more noticeable. As you get older, the skin can thin and lose moisture, causing the overall appearance and color to change. Dry, flaky skin can also make them appear dull. If you are concerned about fading lip color, keep your collagen levels up, use a lip scrub, and moisturize your pout with a balm or lip mask.
