DR. MARNIE Lip Serum sculpts and nourishes for visibly plumper lips. This dermatologist-developed treatment enhances lip definition, structure, and volume, utilizing a cooling Zamac metal applicator. Its clinically proven formula visibly plumps, smooths, and deeply hydrates, actively supporting collagen and softening the look of fine lines and dryness. Available in clear and tinted options, it maintains lip fullness between professional treatments.
