A reformulation of our most-loved hydration serum that instantly hydrates and plumps, while smoothing texture and wrinkles. This new formula has a slight yellow tinge when compared to our previous formula due to the addition of a ceramide blend. This is the natural colour of this new raw material. Hyaluronic Acid 2% + B5 provides instant plumping hydration to give softer, smoother, healthy-looking skin. The lightweight formula replenishes the skin’s hydration levels with all-day results and helps the skin retain moisture to re-plump dry, dehydrated skin. Hyaluronic Acid 2% + B5 also promotes skin suppleness and elasticity, while minimising the appearance of fine dry lines. This formulation contains 5 forms of hyaluronic acid, which helps provide hydration to multiple layers of the surface of the skin. 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 support the skin barrier to keep the skin protected and hydrated. The ceramides used in this formula are known as sphingolipids Pro-vitamin B5 helps support the formation of key skin barrier components like ceramides and fatty acids, which further helps keep moisture locked in, keeping the skin moisturised for longer.
