Dot & Key Peptide Ceramide Lip Balm works by restoring and strengthening your lips’ natural moisture barrier. The ceramides help lock in hydration and prevent moisture loss, keeping lips soft and smooth for long hours. Peptides boost collagen production, which helps improve lip firmness and reduce fine lines. It also contains nourishing butters and natural oils that repair dryness, while providing a healthy, glossy finish. With regular use, it leaves your lips visibly plumper, healthier, and more supple.
