The Hylunäric Chronicles

Sodium Hyaluronate vs Hyaluronic Acid: What’s the Difference?

by Nikola Saric 26 Sep 2023

Hold onto your face masks and toners, skincare enthusiasts, because we're about to dive into the glossy world of hydration heroes: Hyaluronic Acid and Sodium Hyaluronate! 

Oh, and if you just whispered, “Wait, aren’t they the same thing?” 

Well, kind of, but not quite. 

Stick around for the deets, delivered with a side of fun and facts!

The Basics: Getting to Know the Stars

Picture this: You're watching your favorite movie, and two actors stroll onto the scene.

At first glance, they could easily be mistaken for each other. Same swagger, similar fashion sense, both lighting up the screen. 

But as the plot thickens, their individual quirks shine through, revealing they’re not twins, but rather, deeply connected siblings. 

Welcome to the cinematic experience of the skincare universe starring our leading ladies: Hyaluronic Acid (HA) and Sodium Hyaluronate (SH).

Origin Stories Matter

Our story begins with the origin of these molecules. Let's spotlight HA first. 

As a naturally occurring biopolymer, HA finds its roots in various parts of our body, especially the skin. It’s like the body’s personal hydration agent, responsible for retaining water and maintaining skin’s elasticity. 

Think of HA as that natural fountain of youth, working tirelessly behind the scenes, ensuring your skin feels as soft as a baby's cheek.

On the other hand, Sodium Hyaluronate, SH, is the sodium salt derived from our star, HA. Picture it as the savvy younger sibling who's picked up all the best traits of their elder but added a unique spin. 

How does this transformation happen? Through a process called hydrolysis, HA is converted to SH, resulting in a compound with smaller molecular size and slightly different properties.

The Nuanced Science Behind Their Relationship

While they hail from the same family, their chemistry and interactions with the skin differ. Imagine a sugar cube and powdered sugar. Both are sweet, but they dissolve differently in water. 

Similarly, due to its larger molecular structure, HA tends to sit on the skin's surface, creating a protective barrier and drawing moisture from the environment. It acts like a surface shield, warding off external aggressors and keeping your skin feeling hydrated.

SH, with its petite molecular size, doesn't wait around on the surface. Instead, it gets VIP access, penetrating deeper layers of the skin. This allows for enhanced water retention from within, resulting in more profound, lasting hydration. It's the secret agent sneaking in to deliver moisture reinforcements right to the heart of your skin’s cells.

Why Should We Care About the Difference?

Now, you might ask, "Why the skincare science lesson?" Well, understanding these nuances ensures you're picking the right hydration maestro for your specific needs. 

If you're battling environmental factors like harsh winds or dry climates, HA’s surface hydration might be your knight in shining armor. However, if you’re looking for that deep hydration, diving beneath the surface to truly rejuvenate the skin, SH is your go-to hero.

Where it All Begins: Natural Occurrence

You know that super satisfying feeling of finding a $20 bill you forgot about in the pocket of an old jacket? 

Well, imagine discovering that your body has been quietly and tirelessly manufacturing one of the most sought-after skincare ingredients. Yup, welcome to the Hyaluronic Acid (HA) jackpot!

Your Body's Very Own Hydration Station

Every single day, right beneath our very noses (or more accurately, beneath our skin), our bodies are buzzing with HA production. 

This incredible molecule is like nature's way of bestowing upon us a built-in moisturizer. Around 50% of the HA in our bodies is found in our skin. It’s woven between skin cells, where it ensures that our skin remains supple, bouncy, and oh-so-touchable.

Now, think about those moments when your eyes don’t feel dry, even after binge-watching your favorite show, or how your joints have that smooth movement, like a well-oiled hinge. Credit some of that to HA. 

Beyond the skin, HA is the unsung hero in our eyes, providing them with necessary moisture, and in our joints, acting as a buffer and lubricator, ensuring our movements are fluid and pain-free.

The Birth of Sodium Hyaluronate (SH)

Now, while your body is a natural HA-producing marvel, it doesn't directly create Sodium Hyaluronate. Instead, SH is like the next evolution of HA. 

Picture it: Scientists in lab coats, staring at HA and pondering, "How can we take this to the next level?" That's when SH, the salt form of HA, enters the scene. Through scientific processes, they’re able to tweak and refine HA to form SH. 

Why the need, you ask? Well, this derivative offers some qualities that pure HA doesn't possess, especially its ability to delve deeper into the skin.

From Origin to Application: Why It Matters

Understanding this natural occurrence isn't just a cool science fact for your next dinner party; it's pivotal in grasping the significance of these compounds in skincare. 

Recognizing that HA is a natural component of our skin underscores its safety and compatibility. It's like our skin meets an old friend every time we apply an HA-infused product.

On the other hand, the creation of SH from HA showcases human ingenuity. By observing nature and then enhancing it, we’ve tailored a molecule with specific benefits, especially for deeper hydration needs.

Diving Deeper: The Science Behind the Magic

Tuning Into Molecular Weight: The Unsung Melody

Now, 'molecular weight' might sound like a term that belongs in a late-night college study session, but trust me, it's more like the VIP ticket to understanding our skin's jam. 

In the simplest of terms, molecular weight gives us a peek into the size of a molecule. 

Why does size matter? Well, in the skincare universe, size dictates how deep a molecule can groove into your skin.

HA: The Surface Maestro

Enter Hyaluronic Acid (HA). With its more substantial molecular weight, it's like the headliner at a music festival – prominent and unmissable. 

When you apply HA, it doesn't plunge deep into your skin. Instead, it lovingly lingers on the surface, serenading the outer layers. 

This isn't laziness; it's by design. HA's role is like that of a protective older sibling or, as we previously painted, the lifeguard by the pool. 

Its large molecular size ensures it forms a protective, hydrating film on your skin, like a melodious tune that envelops and uplifts the crowd. This is your quick hydration fix, defending against daily assaults like dry air and pollutants.

SH: The Deep-Sea Virtuoso

Now, imagine a versatile musician, one who's not just content playing on the grand stage but also thrills in exploring underground music scenes. 

That's Sodium Hyaluronate (SH) for you. With a molecular weight that's like a catchy, lightweight tune, SH doesn't just stop at the surface. It has the finesse and agility to weave between skin cells, diving deeper and reaching those inner layers, hydrating from the inside out. 

If HA is the lifeguard, SH is certainly the intrepid deep-sea diver, navigating the profound mysteries of your skin's oceanic depths.

Harmonizing Your Skin's Needs

When you grasp this dance of molecular weights, you're no longer just applying skincare; you're orchestrating a symphony. You’ll begin to understand why certain products emphasize SH over HA and vice versa. 

Depending on your skin's needs – whether it's a surface hydration boost or a deep dive of moisture – you can now pick your products like a maestro choosing the right notes for a song.

What's the Hype? Benefits Breakdown

HA’s Rap Sheet

  1. Surface Hydration: It's easy to overlook those top layers of skin, but not for our surface siren, HA. Much like the morning dew gracing the blades of fresh grass, HA hydrates the skin's exterior. That first touch, that initial feel of softness when your fingers graze your cheeks? All thanks to this hydration maestro. Surface might sound superficial, but it’s what the world sees first!

  2. Plumping Action: Ever look in the mirror after a spa day or a refreshing face mask and think, "Is that me, or a hydrated Greek goddess?" HA plays a crucial role in that transformation. By holding onto water at the skin's frontier, HA turns it into a plush, pillowy dream. It's like treating your skin to a VIP hydration lounge, where every cell gets that plush, luxury sofa experience. Yes, it makes you radiate that elusive, "I've just downed a gallon of the purest spring water" glow.

  3. Barrier Booster: Not just content with offering hydration, HA takes it up a notch. By forming a protective film, it's like your skin’s personal shield against environmental assaults. Think of HA as that trusty umbrella on a drizzly day, ensuring your skin remains unscathed from the dryness and external aggressors.

SH’s Rap Sheet

  1. Deep Dive Hydration: Here’s where SH flexes its finesse. It's not just your casual acquaintance; it's the kind of friend who remembers the little things, like your mom’s favorite recipe or that embarrassing story from third grade. SH doesn’t just knock on your skin’s door; it gets invited in, delves deep, and ensures even those often-neglected inner layers are hydrated. It's meticulous, attentive, and oh-so-thorough.

  2. Long-lasting Stay: Ever had a song on loop in your mind, playing endlessly, whether you're in the shower or grocery shopping? SH’s effects are just as memorable. Due to its knack for diving deep, it doesn’t evaporate or wash away easily. It lingers, ensuring your skin reaps the benefits longer. Think of it as the hydration encore your skin didn’t know it needed.

  3. Enhanced Skin Health: Digging deep isn’t just about hydration. By reaching the inner sanctum of your skin, SH also supports skin health from within. It's like having a health coach for your skin cells, ensuring they're not just looking good but genuinely thriving.

  4. Flexibility and Elasticity Dynamo: Remember those moments when your skin feels so supple it could rival the flexibility of a gymnast? SH deserves some accolades. It's not just about surface-level bounce but ensuring the foundational layers of your skin remain flexible and resilient.

How To Pick What's Right for You?

This isn’t a one-size-fits-all deal. If you’re living for that instant fresh feel, HA might be your go-to. But if you’re looking to treat your skin to lasting hydration, make some room on your shelf for SH.

Sensitive Soul? Here’s the Lowdown

Both HA and SH are generally considered safe for all skin types. 

But, like any close-knit family, every member has its quirks. 

HA: The Gentle Embrace

HA, with its larger-than-life molecular persona, is like that kind friend who respects personal boundaries. 

As we’ve seen, it doesn’t dive too deep, preferring to grace your skin's surface, making it a darling for those with sensitive spirits. Its hydrating embrace is gentle, soft, and non-intrusive. Think of HA as the soothing lullaby, delicate notes that serenade without overwhelming.

SH: The Eager Explorer

Enter SH, the intrepid molecule with zest and zeal. It’s passionate about its mission - to penetrate, nourish, and hydrate the deeper layers of your skin. 

But, with great passion can sometimes come a tad too much enthusiasm. For those blessed with the sensitivity of a poet's soul, SH might sometimes be the equivalent of an overeager fan, diving a bit too deep, a tad too quickly.

That doesn’t mean SH is a no-go for sensitive skin types, but it's like introducing your pet to a new environment – gradual acclimatization can be key. Due to its smaller molecular structure, SH can sometimes be a bit too adventurous for some, leading to reactions in particularly sensitive individuals.

Patch Test – The First Date

Before you commit to any skincare relationship, it's vital to have that 'first date'. 

In the skincare world, this is known as a patch test. Find a little spot on your forearm, apply a dab of the product, and wait for 24 hours. 

It’s like having coffee before committing to a dinner date. This helps you understand how your skin vibes with the product. If all's calm on the western front, you're probably good to go. 

If there's a tiff (read: redness, itching, swelling), it's best to hold off and consult an expert.
