LRP Hyalu B5 serum is formulated with two pure forms of Hyaluronic Acid for maximum and clinically proven optimal efficacy. The High Molecular Weight Hyaluronic Acid creates a surface barrier on the skin to hold in moisture and re-plump fine lines and wrinkles while the Low Molecular Weight Hyaluronic Acid penetrates the skin for a deep re-plumping action from within. Hyalu B5 also facilitates skin repair by combining Hyaluronic Acid with Vitamin B5. The concentrated serum instantly soothes with its luxurious aqua-gel formula, while plumping and facilitating skin repair.
