If you’ve spent any time scrolling through skincare TikTok or browsing beauty aisles lately, you’ve seen the word “hyaluronic acid” everywhere in serums, masks, moisturisers, and even foundations.
But here’s the truth: hyaluronic acid isn’t new. Your body already makes it naturally. It’s found in your eyes, joints, and skin, working quietly behind the scenes to keep everything lubricated, cushioned, and hydrated.
So why is it suddenly the star of every skincare shelf? Because modern research has revealed that when formulated correctly, hyaluronic acid can transform how your skin looks and feels instantly and long-term.
Before we get into how, let’s start with what it actually is.
What Is Hyaluronic Acid?
Despite the intimidating name, hyaluronic acid (HA) is a gentle, sugar-based molecule known scientifically as a glycosaminoglycan. It acts like a sponge, drawing and holding onto moisture both within your skin and from the environment around you. Your skin is also made of it.
In fact, it’s famous for its ability to hold up to 1,000 times its weight in water. When your skin is well hydrated, it looks plumper, smoother, and more radiant. When it’s not, fine lines become more visible, texture feels rougher, and your barrier weakens.
“Hyaluronic acid is one of nature’s most effective moisture regulators. Its unique molecular structure allows it to bind water where the skin needs it most, helping maintain smoothness, elasticity, and comfort. In balanced formulations, it supports deep hydration without overwhelming the skin or clogging pores.”
— Dr George Thouas, Skincare Development Scientist at Salvarity

How Hyaluronic Acid Works on the Skin?
Think of your skin like a sponge. When it’s dry, it looks deflated and dull. Add water, and it becomes full and flexible again. That’s exactly what hyaluronic acid does, it attracts and binds water, restoring bounce and elasticity.
Inside your skin, HA molecules act as humectants, pulling moisture from the air and deeper skin layers into the outermost layer (the stratum corneum). This reduces transepidermal water loss (TEWL),one of the main causes of dryness and loss of elasticity..
The result? Instant plumpness and long-term barrier support.
Key Benefits of Hyaluronic Acid for Skin Health
No matter your age or skin type, hyaluronic acid offers a long list of benefits that go beyond hydration:
-
Deep Hydration: Keeps the outer layers of your skin hydrated, soft, and smooth.
-
Plumping Power: Minimises the appearance of fine lines caused by dehydration.
-
Barrier Support: Strengthens your skin’s natural defence against pollution, UV damage and bacteria
-
Balanced Skin: Works for oily, dry, and combination skin without clogging pores.
-
Repair and Recovery: Helps the skin heal effectively and reduces visible redness.
Because it’s naturally present in the body, it’s well-tolerated even by sensitive or breakout-prone skin.

Where You’ll Find Hyaluronic Acid (and How to Use It)
You’ll see hyaluronic acid featured in nearly every skincare category:
- Serums: Lightweight, water-based, and perfect for daily layering.Moisturisers:
-
Combining HA with ceramides or lightweight oils to seal in hydration.
-
Sheet Masks: Offer a quick plumping effect before events or makeup.
-
Eye Creams: Target delicate skin zones prone to fine lines and dullness.
From Nature to Biotech: The Evolution of Hyaluronic Acid
Here’s something most people don’t know: decades ago, HA was extracted from rooster combs. Today, thanks to biotechnology, it’s made sustainably through fermentation using safe, vegan processes.
This innovation not only ensures purity and consistency but it aligns perfectly with modern, eco-conscious skincare standards.
As dermatologist Dr Amy Weiss explains in the American Academy of Dermatology, “biotech-derived hyaluronic acid has revolutionised skincare safety and efficacy.”
How to Layer Hyaluronic Acid in Your Routine
Skincare layering can feel like a puzzle but HA makes it easy. Here’s how to get it right:
Morning:
-
Cleanse with a gentle, pH-balanced cleanser.
-
Apply HA serum while skin is damp.
-
Seal with moisturiser and finish with SPF 50.
Night:
-
Cleanse and optionally exfoliate.
-
Apply HA serum, then a barrier-repairing moisturiser.
-
If you use retinol, layer HA after to reduce dryness.
This technique keeps moisture locked in all day and night.
Who Should Use Hyaluronic Acid (and Who Shouldn’t)
The beauty of HA is that it suits almost everyone:
-
Teens: Light, water-based hydration without heaviness.
-
Adults: Prevents early dehydration lines.
-
Mature skin: Improves suppleness and texture.
-
Sensitive skin: Non-irritating and fragrance-free in most formulas.
However, those with severe dryness in low-humidity environments should layer HA under a cream, rather than alone.
Myths & Marketing: What HA Can and Can’t Do
You’ve probably heard that HA “fills wrinkles instantly.”
That’s half-true. Topical HA plumps dehydration lines, but it doesn’t physically fill deep wrinkles the way injectable fillers do.
And that “1000x its weight in water” claim?
It’s a lab figure, not how it functions on your face. Real-world effectiveness depends on molecular size, humidity, and formulation.
These myths make for great marketing but poor skincare advice.
The 1000x Myth & The Science of Hydration
Let’s dig into that number a little more. In lab conditions, 1 gram of HA can bind 1 litre of water.
But once on the skin, the available moisture depends on the surrounding air and the presence of a sealant (your moisturiser).
That’s why dermatologists call HA a “smart hydrator”. It works best when supported by the right environment.
Final Thoughts: Why Hyaluronic Acid Is Here to Stay
The hype around hyaluronic acid isn’t going anywhere because it’s one of the few ingredients that delivers both instant and lasting results.
It’s the foundation of healthy skin: hydration, elasticity, and balance.
But remember, even the best ingredient is only as good as how you use it. Pair it with the right routine, environment, and sealant, and you’ll see why dermatologists call HA a “skin essential.”
So the next time you reach for that serum, do it with confidence. You’re feeding your skin what it truly craves: water, balance, and care.

FAQs About Hyaluronic Acid
Is hyaluronic acid good for acne-prone skin?
Yes. It provides hydration without clogging pores. In fact, when skin is properly hydrated, oil production can stabilise, reducing breakouts.
Can I use HA every day?
Absolutely. You can even use it twice daily, as long as you seal it with moisturiser, depending on which type of climate you live in.
Does hyaluronic acid make skin peel?
No, HA doesn’t exfoliate. If peeling occurs, it’s usually due to over-exfoliation or product buildup.
Can I use HA with retinol?
Yes, in fact, it’s one of the best buffers against retinol-related dryness.
Is there such a thing as too much HA?
Technically yes. Over-layering multiple HA products can lead to stickiness and pilling. Keep it simple: one serum and one moisturiser is enough.
