New from The Ordinary. Hyaluronic Acid 2% + B5 provides instant hydration to give softer, smoother, healthy-looking skin. The lightweight formula replenishes the skin’s hydration with all-day results, and helps the skin retain moisture to re-plump dry, dehydrated skin. Hyaluronic Acid 2% + B5 also promotes visible skin suppleness and elasticity, while minimising the appearance of fine dry lines. This formulation contains 5 forms of hyaluronic acid. Hyaluronic acid is a humectant found naturally in the skin where it binds to water. The forms included are low-, medium- and high-molecular- weight molecules, a HA crosspolymer, and hydrolyzed HA. The formulation also contains ceramides to help keep moisture locked in. Ceramides are lipids (fatty molecules) found naturally in the skin that help protect the skin barrier. The ceramides used in this formula are known as sphingolipids. Pro-vitamin B5 keeps the skin moisturised for longer. Vegan.
