Anua PDRN Lip Serum is a nourishing Korean lip serum designed to repair, hydrate, smooth, and visibly plump dry or chapped lips with a glossy non sticky finish. It is made for lips affected by dryness, flaking, fine lines, reduced fullness, environmental stress, sun exposure, air conditioning, and daily moisture loss. The formula is powered by PDRN, a premium skin renewal ingredient used in Korean skincare to support lip repair, improve resilience, and promote a healthier looking lip barrier. Hydrolyzed collagen and peptides help improve the look of lip density and definition, while hyaluronic acid and ceramides lock in moisture and create a breathable hydration shield for long lasting comfort. The rich cushion like texture coats the lips smoothly, helping soften rough patches, reduce the appearance of lip lines, and leave lips looking fuller, juicier, and more radiant. It can be used alone for a glass lips finish, under lipstick as a smoothing primer, or as an overnight lip mask for intensive recovery and moisture care.
