The lightweight and fast absorbing Hyaluronic Serum is Aspect Dr’s answer to dehydration. A unique blend of hyaluronic acid that effectively replenishes the skin’s moisture content. Hyaluronic acid naturally exists within the skin, and it has the potential to bind to and hold over 1000 times its own weight in water. Hyaluronic Serum contains both high and low molecular weights of sodium hyaluronate, which addresses dehydration by delivering hyaluronic acid to varying levels within the skin. Niacinamide assists with improving the skin barrier, which is essential when aiming to lock moisture into the epidermis, and also reduces transepidermal water loss. The addition of panthenol also encourages skin barrier improvement, and has the extra benefit of being very hygroscopic to allow for binding to and locking in of water within the epidermis to improve skin hydration. Hyaluronic Serum also contains antioxidants and aloe vera leaf juice to assist with the strengthening, soothing and protection of sensitive, dehydrated, dry and reactive skin types.
