Component of skin tissue. Synthetic variations are used in skincare products to function as a superior skin-replenishing ingredient. Hyaluronic acid has restorative abilities and can boost skin’s moisture content, soothe, and defend against moisture loss. It is capable of holding up to 1,000 times its own weight in water, making it an optimal hydrator for all skin types.
In addition to its function as a superior skin-restoring ingredient, hyaluronic acid also provides an antioxidant defense against environmental assault. Consumed orally via supplements, hyaluronic acid (both low and high molecular weights) can improve skin’s ability to stay hydrated, visibly decrease wrinkle depth and surface roughness, and help reinforce skin’s protective barrier.
