Our #1 bestseller, this is a daily essential for every routine and helps your other skincare work harder. Clinically proven to deliver instant and lasting hydration, this non-tacky hydrating serum leaves skin feeling plump, smooth and healthy. ​

Formulated with 2% multi-molecular Hyaluronic Acid, this powerful moisture-binding ingredient can hold up to 1000x its weight in water, which is essential for maintaining skin hydration and plumpness. Lightweight and rapidly absorbed on contact with the skin, the combination of high and low molecular weight HA helps the serum deliver hydration across multiple layers of the skin's surface. ​ ​

Suitable for all skin types, we love it for its non-sticky or tacky texture. It glides on and instantly melts into the skin leaving you with a hydrated, dewy base. Helping to combat dry skin, improve the appearance of fine lines and helps maintain an effective skin barrier, it’s a must-have for every skincare routine.​

    Soaks in quickly

    This serum soaks in fast and isn’t sticky. I don’t feel like there is anything in my face which I like bc it doesn’t feel heavy when I layer my skincare.
