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.​

    Fantastic Serum!

    Really good Serum for someone who suffers with sensitive skin. Helps give my skin moisture after using Salicylic Acid Cleanser. Gets rid of the dry skin before I apply the Omega Water Cream.

    Must-Have!

    This is a staple in my routine! Whenever I get lazy with the skin routine, which does happen, I simply cleanse and use the hyaluronic serum to keep my skin hydrated at the very least.
