Revitalift Hyaluronic Acid Anti-Wrinkle Serum. Formulated with 1.5% Pure Concentrated Micro-Epidermic Hyaluronic Acid, our highest concentration of pure Hyaluronic Acid. The serum intensely hydrates and is proven to replump fine lines and wrinkles in just 1 hour. The formula contains two types of Hyaluronic Acid for high performance. Macro Hyaluronic Acid molecules which are larger and sit at the top of the skin's surface to boost hydration, and Micro Hyaluronic Acid molecules which are smaller and penetrate deeper into the skin's epidermis, to boost from within. The formula penetrates through the skin's surface, helping to replump fine lines and wrinkles from within. The serum deeply hydrates skin, leaving skin visibly plumper and fine lines reduced.
