Hydroderm Lip Enhancer is the painless, easy way to plump up your lips – wherever and whenever you please. The Lip Enhancer is a lightweight gloss that you brush on to your lips. This Lip Enhancer works in two important ways: First, it produces an immediate increase in hydration, causing a noticeable swelling of the lips. Second, it has an instant effect just below the surface, so your lips get that “bee stung†look and stay soft.
