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.​

    I liked that it melted the make up nicley and removed my waterproof mascara but it left a residue on my skin and it got me concern because I have oil skin so im not sure if i would purchase the full size one yet. I also felt the little im assuming oatmeal grains, which i guess helps exfoliate, but i didn't like the residue. However, it did come off after i showered my soap.

    I started using this product almost 4 years ago and it saved my skin. I had a severely damaged skin barrier, active breakouts, oily skin, texture, acne scars, and clogged pores. This product calmed my skin and allowed it to balance out. It’s a hydrating product that doesn’t leave my skin oily and feels good when I put it on. It also never broke me out!
