Laneige Lip Sleeping Mask in Berry, the original scent, is a leave-on lip mask with a balm texture. You apply it before bed so it can hydrate, soften and smooth your lips overnight.

The formula combines Berry Fruit Complex, which is rich in antioxidants, with shea butter, murumuru seed butter and coconut oil to help nourish and keep in moisture. Vitamin C helps protect against external aggressors. The brand says it gently exfoliates flaky skin on the lips, so they feel softer and smoother in the morning.

Laneige reports 12-hour hydration after one use and 94% less flaky lips after two weeks, based on instrumental tests on 33 people. You can also wear a thin layer during the day or before lipstick. The formula contains fragrance.
