What Is Hyaluronic Acid — And Are They All the Same?
Dehydrated, flat, or tight skin? You’re not imagining it.
You apply your moisturiser. You drink more water.
But within hours, your skin still feels tight, dull, or deflated — especially by mid-afternoon.
It’s one of the most common frustrations in any skincare routine.
And often, the missing link is Hyaluronic Acid… but not the kind most people think.
So why does the skin lose moisture so quickly?
Despite the word acid, Hyaluronic Acid isn’t harsh at all.
It’s a natural molecule inside your skin. Its job is simple:
Draw moisture in — and keep it there.
Think of your skin like a glass of water sealed with cling film.
When the seal is intact, water stays put.
The skin looks:
- Plump
- Smooth
- Fresh
- Youthful
This molecule lives in three layers of the skin:
- The top layer (barrier)
- The middle layer (water reserves)
- The deeper layers (supporting structural fibres)
It keeps each level comfortably hydrated… when it reaches them.
The problem: most serums work only on the skin surface
Here’s something many people aren’t told:
About 95% of these serums use just high molecular weight molecules, which means:
- The molecule is too large to penetrate deeper skin layers
- It remains on the surface
- Hydration feels good but is temporary
These serums make skin feel good at first… but the deeper dehydration is left unaddressed.
This explains why some products seem to “stop working”, or why skin looks tired even with use.
Here’s where multi-weight hyaluronic acid changes everything
To hydrate skin fully — not just the surface — you need three different molecular sizes working together.
This is an evolution of ingredients, not a trend.
High molecular weight
- Creates a moisture-sealing film on the skin’s surface
Medium molecular weight
- Replenishes the skin’s internal water reservoirs
Low molecular weight
- Travels to deeper layers, supporting structural fibres where ageing begins
A multi-weight formula hydrates every part of your skin, from protective film to deeper fibres.
What happens when all three molecular sizes work together?
The transformation becomes visible — not just felt.
A true multi-weight formula can help:
- Plump skin at every level, not just the surface
- Fill water reservoirs, improving elasticity
- Soften dehydration lines, making skin look smoother
- Support deeper layers, where firmness and ageing fibres sit
- Improve long-lasting comfort, beyond temporary glow
- Enhance the performance of your full skincare routine
Skin looks fresher, feels fuller, and stays hydrated much longer.
