The Reservoir

Hyaluronic Acid

A hydration molecule that holds up to 1000× its weight in water.

What it is

In plain language

Hyaluronic acid is a glycosaminoglycan that occurs naturally in the skin, eyes and connective tissue. Topical hyaluronic acid replenishes the moisture reservoir that depletes with age, weather and over-cleansing.

The science

How it actually works

Hyaluronic acid binds water within the extracellular matrix. Multi-weight formulations layer high-molecular-weight HA on the skin surface to reduce evaporation, while low-molecular-weight HA penetrates deeper layers to plump from within.

Frequently Asked

Your questions, answered

Should I apply it to damp or dry skin?
Always to damp skin. Hyaluronic acid draws moisture from its surroundings — applied to dry skin in dry climates it can pull moisture out of the deeper layers.
Can I use it with retinol?
Yes — it actually buffers retinol-related dryness beautifully.
Does it replace a moisturiser?
No. It holds water, but you still need a moisturiser or oil to seal it in.
