Lightweight hydration for smooth, plump-looking skin
Give your skin an instant boost of moisture with our Hyaluronic Acid Hydration Boost Serum, designed to hydrate and soften without feeling heavy or sticky.
Four ingredients. Nothing else.
Water, sodium hyaluronate at 1%, benzyl alcohol, and dehydroacetic acid. That's the entire formula. If you have sensitive skin, this matters more than any marketing claim on the label. Thirty ingredients means thirty chances to react. Four means four.
We state the concentration because most brands won't tell you how much hyaluronic acid is actually in the bottle.

- Formulated for sensitive and reactive skin, and gentle enough for daily use

About hyaluronic acid
Hyaluronic acid is a humectant, which means it attracts and holds moisture at the skin's surface. It can retain up to 1,000 times its weight in water. It occurs naturally in skin, and levels tend to decline with age and environmental exposure, which is why it's become a staple in hydrating skincare.
At 1% pure sodium hyaluronate, this is a real concentration rather than a trace amount added for the ingredient list.
Best for
Normal, dry, oily, combination, and sensitive skin. Particularly suited to reactive skin that hasn't tolerated other serums well.
If you're building a routine for reactive skin, you can see our full range of serums for sensitive skin here.
How to use
Apply a few drops to clean, slightly damp skin. Follow with your moisturizer to lock in hydration. Use morning and night.
