A lip mask is a nourishing treatment designed to hydrate and repair dry or chapped lips. Typically applied before bedtime, it creates a barrier that locks in moisture and helps to soften the lips overnight. Many lip masks are infused with ingredients like hyaluronic acid, shea butter, or natural oils to provide intense hydration and improve the overall texture of the lips. Using a lip mask regularly can enhance your lip care routine, leaving your lips feeling smooth, plump, and revitalized.
