Uriage Eau Thermale Hyaluronic Acid Booster Serum is a luxurious facial serum designed to hydrate, plump, and moisturize the skin. Formulated with 1.5% pure and natural hyaluronic acid, as well as Uriage thermal water, marshmallow flower extract, and aquaxyl, this serum targets dryness, fine lines, discomfort, and dullness. Hyaluronic acid creates a protective film on the skin's surface, smoothing fine lines and leaving the skin luminous and soft. The different molecular weights of hyaluronic acid work together to hydrate, plump, tone, and improve elasticity in the skin. Aquaxyl and marshmallow flower extract boost hydration and protect the skin from external aggressors. With continued use, the skin becomes progressively and durably hydrated, resulting in plumped, smoothed, and hydrated skin with a velvety finish.The lightweight, non-greasy, and non-sticky texture of the serum ensures a pleasant application experience. The signature fragrance of the EAU THERMALE range adds a touch of luxury to the skincare routine. In addition to its hydrating properties, Uriage Thermal Water softens and soothes all skin types, including sensitive skin, thanks to the exclusive Uriage patents (LN Modul and Barrier Patent) that protect and enhance the skin's natural defenses.
