Hyaluronic Acid Hydrating Serum

Multi-weight hyaluronic acid for deep, lasting hydration.

Hyaluronic Acid | 1% Niacinamide

Size:

50ml

Intense hydration that actually works. This multi-weight hyaluronic acid serum penetrates multiple skin layers to deliver deep, lasting moisture. Sodium hyaluronate (low molecular weight) plumps from within whilst hyaluronic acid (high molecular weight) locks moisture at the surface. Skin feels instantly smoother, softer, and more supple. Non-greasy, fragrance-free formula suitable for even the most sensitive skin. Layer under moisturiser for maximum hydration or use alone for lightweight moisture.

The Science

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].
