A lip mask is a beauty product designed to moisturize and soften the lips. It is typically a gel mask worn on the lips for a set period of time, with some designed to be worn overnight. Lip masks work to hydrate the lips by infusing a combination of vitamins, minerals, and other nourishing ingredients. They are especially beneficial for combatting dryness and can make the lips look fuller and plumper. Lip masks are similar to lip balms but are more intensive and provide longer-lasting hydration. They are also known to be popular in Asian beauty routines and are considered a relaxing and luxurious treatment. Some well-known lip masks include the Laneige Lip Sleeping Mask and the Tatcha Kissu Lip Mask
