Hyaluronic Acid for Skin: Benefits, Uses and How It Works

Hyaluronic acid might be the most talked-about hydrating ingredient in skincare — and unlike a lot of trending actives, it earns the hype. Here's what it actually does, how it works, and why you'll find it across most of our range.

What is hyaluronic acid?

Hyaluronic acid is a humectant — an ingredient that draws water in and holds onto it. It's naturally found in your skin already, where it helps keep tissue hydrated and plump. What goes into skincare formulas is typically derived through fermentation, not animal sources, despite what the name might suggest.

The standout property: hyaluronic acid can hold significantly more water than its own weight, which is why it's become the go-to hydrator across nearly every skin type and concern.

What does hyaluronic acid do for skin?

It draws in and holds moisture. As a humectant, hyaluronic acid pulls water from the environment (or from deeper skin layers, in humid conditions) and binds it at the surface, keeping skin hydrated rather than just coated.

It supports a plumper, smoother look. Well-hydrated skin appears more supple and can make fine lines from dehydration look less pronounced — though this is a hydration effect, not a wrinkle-erasing one.

It works across skin types. Because it hydrates without adding oil, hyaluronic acid suits oily, dry, and combination skin alike — it's not an ingredient you need to avoid based on skin type.

It layers well with other actives. Hyaluronic acid doesn't compete with retinol, vitamin C, or acids — it's commonly formulated alongside them precisely because it helps offset the dryness those actives can sometimes cause.

Different molecular weights: why it matters

Not all hyaluronic acid behaves the same way. Lower molecular weight versions penetrate deeper into skin, while higher molecular weight versions sit on the surface and form a hydrating film. Many formulas — including ours — use a blend, so hydration happens at multiple levels rather than just the surface.

You'll find hyaluronic acid in our Antioxidant Moisturiser, Retinol Eye Cream, Retinol & Peptide Night Repair Cream, Botanical Antioxidant Serum, Glow Serum, Calming Collagen Tonic, Calming Collagen Serum, and AHA/BHA Resurfacing Serum — it's one of the most consistent ingredients across our entire range.

Does hyaluronic acid have any downsides?

The one real caveat: in very dry, low-humidity environments, hyaluronic acid can pull moisture from deeper skin layers if there's no water in the air for it to draw from — which can occasionally leave skin feeling drier rather than more hydrated. The fix is simple: always apply it to damp skin, and follow with a moisturiser to lock the hydration in.

Is hyaluronic acid safe for sensitive skin?

Yes — hyaluronic acid is generally very well tolerated and is often recommended specifically for reactive or sensitive skin, since it hydrates without the potential irritation of harsher actives. As always, individual reactions are possible, so patch test if you're introducing any new product.

How to use hyaluronic acid for best results

• Apply to damp skin, not dry — it needs some water to draw from.
• Follow with a moisturiser to seal the hydration in.
• Layer it under, not over, heavier creams and oils.
• It works well both morning and night, and pairs safely with actives like retinol and vitamin C.
