How to use

When to Use: AM and PM

How to Use:

Step 1: Apply 2-3 drops to a **damp** face and neck after cleansing. Applying to damp skin helps the hyaluronic acid to draw moisture into the skin more effectively.
Step 2: Gently pat into the skin.
Step 3: Immediately follow with your next serum or moisturiser to seal in the hydration. Don't let it dry on its own!

Pro Tip: You can use this serum before any other serum in your routine to give your skin a hydration boost.

The research

The Science Behind Deep Hydration

Multi-Weight Hyaluronic Acid: Hyaluronic Acid (HA) is a molecule that occurs naturally in your skin and can hold up to 1,000 times its weight in water. Our formula uses multiple molecular weights of HA to deliver multi-level hydration, a strategy supported by clinical research:

High-Weight HA: Sits on the surface of the skin, providing immediate hydration and smoothing the appearance of fine lines [1].
Low-Weight HA: Studies have shown that lower molecular weight HA (20-300 kDa) can penetrate the skin's outer layers, delivering sustained hydration from within [2]. This helps to plump the skin for a bouncy, healthy look.

1% Niacinamide (Vitamin B3): We've included a supportive 1% concentration of Niacinamide to help strengthen the skin barrier. A healthy barrier is crucial for locking in the hydration delivered by Hyaluronic Acid, preventing transepidermal water loss (TEWL) [3].

Why it works: By providing both surface-level and deep hydration while simultaneously strengthening the skin barrier, this serum doesn't just add moisture—it helps your skin hold onto it. Clinical trials have demonstrated that topical HA serums can increase skin hydration by as much as 55% [4].
