COSRX Full Fit Propolis Lip Sleeping Mask is a nourishing overnight treatment formulated with a Honey-6 Complex, including propolis extract and other honey-derived ingredients. This rich, non-sticky mask deeply hydrates and repairs dry, chapped lips while you sleep, leaving them soft, plump, and supple by morning. Its dense, honey-like texture creates a protective barrier, locking in moisture for lasting comfort.
