Hyaluronic Acid 100 is a powerful humectant (holds moisture) and is known for its ability to add long-lasting hydration. This lightweight, fast-absorbing serum is ideal for all skin types but particularly for dry skin. This serum is fast acting, boosting the skin's radiance and hydration and thus preventing the appearance of fine lines. Also containing ceramide, it helps strengthen the skin's barrier preventing moisture loss.  The formulation for this multitasking serum also includes raspberry extract, which is an antioxidant that protects against free radical damage.
