LANEIGE Lip Sleeping Mask Berry 20g is an overnight mask specially designed to moisturize and revitalize dry, chapped lips while you sleep. Enriched with Berry Mix Complex™, a blend of berry extracts rich in vitamin C and antioxidants, it helps gently exfoliate dead skin cells and reveal smoother, more supple lips upon waking. Its melt-in balm texture forms a protective layer that seals in moisture throughout the night.
