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.​

    Good serum

    The texture isn't too thick and the serum feels light on my skin. I've been using this serum for a year or two and have had no complaints

    Amazing hydration

    I have very dry skin so when the Inkey list gave me this bottle for free with my first purchase it was like discovering a whole new world.

    Before using this super-hydration-in-a-bottle I truly was a wash-face-with-soap-tablet, use-eye-cream and end-with-a-moisturiser-for-dry skin girlie but this gift opened my eyes as to how crucial and effective hydrator and treatment serums can be. I love the way you can just use a tiny amount on the palm of your hand and start putting it all over your face and neck: no fuss, no mess, takes literally three to five seconds.

    Gone is the tightness of my dry skin and I even started to get compliments on how glowy and healthy I looked (I suffer from several chronic illnesses and chronic pain so this felt truly amazing). If you're after a quick, easy but very effective hydrating serum this is for you. But it can also be a wonderful gateway into discovering just how much serums can do for you: Today I still use this (now in the 100ml bottle) as well as the ectoin hydro-barrier serum, the ceramide serum and glucoside serum both AM and PM, which has done wonders for both the symptoms as well as the look and feel of my face.

    Not everybody needs such an intense hydration routine as me of course, I just wanted to share what works best for me as someone with sensitive, not dehydrated but very dry skin so others who suffer from what I…
