Sinks twice as deep into your skin as standard hyaluronic acid - delivering hydration below the surface, not just sitting on top
The tiny hyaluronic acid molecules in this formula slip into the skin far more easily than standard, bigger ones. It is the difference between hydration that soaks in and hydration that just sits there.

Frequently Asked Questions
Everything you need to know before adding the Hydration Booster to your routine.
Will it feel heavy or sticky?
No. It's a lightweight, fast-absorbing, water-based formula designed to sink in without leaving a sticky residue.
Is it suitable for oily or acne-prone skin?
Yes. Hyaluronic Acid is oil-free and non-comedogenic, making it suitable for all skin types, including oily and acne-prone skin.
Why does it use four different types of Hyaluronic Acid instead of one?
Different molecular weights of Hyaluronic Acid behave differently on skin. Some sit on the surface for an instant plumping effect, others penetrate deeper to hydrate below the surface. Layering multiple weights hydrates more completely than a single form can.
Why does my skin need extra hydration as I get older?
Skin's own Hyaluronic Acid naturally declines with age, by around 6% every decade, and by roughly half by age 50. Topping up levels can help support the hydration skin is naturally losing.
Can I use it under makeup or SPF?
Yes. Its lightweight, fast-absorbing texture makes it a good base layer under makeup and sunscreen
How often should I use it?
Apply morning and evening as part of your Daily Skin Ritual, to clean skin before your Sea Buckthorn Serum.
What order should I apply it in with the serum?
Apply the Hydration Booster first to clean skin, follow with Sea Buckthorn Serum, then finish with your moisturiser.
Why pair it with Sea Buckthorn Serum?
Hydration works best when it's both delivered and retained. The Hydration Booster draws moisture into the skin, while Sea Buckthorn helps lock it in by supporting a healthy, resilient skin barrier.
