The Types of Hyaluronic Acid: Is Sodium Hyaluronate Different than Hyaluronic Acid?

3 Mins read


In the world of skincare, the buzz around hyaluronic acid is undeniable. It’s a staple in most hydrating products, promising to deliver unparalleled moisture retention and hydration to the skin. However, not all types of hyaluronic acid are created equal. Let’s dive into the intricacies of the three main types: Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, and Hyaluronic Acid Salts.

Understanding the Origins: Hyaluronic Acid

The “parent molecule” of the trio, Hyaluronic Acid, or hyaluronan, boasts the highest molecular weight.

Known for its exceptional moisture retention capabilities, it can hold up to 1000 times its weight in water. When applied topically, it acts as both an occlusive and a humectant, forming a protective film on the skin while attracting and holding onto water.

In injectable forms, high molecular weight Hyaluronic Acid not only takes longer to break down but also stimulates the production of additional hyaluronic acid, collagen, and elastin, promoting skin regeneration.

If you spot only “hyaluronic acid” on the ingredients list, chances are it’s the higher molecular weight variant.

Similar yet Different: Hydrolyzed Hyaluronic Acid

Enter Hydrolyzed Hyaluronic Acid, a child of the parent molecule.

The key distinction of hydrolyzed hyaluronic acid from other types of hyaluronic acid lies in its processing technique. Through hydrolysis, the polymer is broken down into specific size ranges, offering formulators more control over molecular weight. This controlled breakdown enhances penetration into the skin’s sublayers, providing deeper moisturization.

However, a note of caution: hydrolyzed hyaluronic acid in water-based formulations can undergo further breakdown over time, potentially transitioning to a lower molecular weight than the formulator intended.

The Lightweight Contender: Hyaluronic Acid Salts

Moving on to the lightweights, Hyaluronic Acid Salts, particularly sodium hyaluronate, take center stage. With the lowest molecular weight, they effortlessly blend into beauty formulations without causing significant viscosity changes. Found naturally in the body, these salts, when isolated from hyaluronic acid. Due to their size, they can penetrate down to the dermis like glycerin.

This is the only form of hyaluronic acid that has consistent scientific evidence of its ability to penetrate into the dermis.

Noteworthy is their stability in water-based formulations, degrading at a slower pace than regular hyaluronic acid or hydrolyzed hyaluronic acid.

For added stability and benefits, enter Hyaluronic Acid Salt Crosspolymers.

Stability Meets Performance: Hyaluronic Acid Salt Crosspolymers

Crafted for stability and performance, Hyaluronic Acid Salt Crosspolymers combine the stability of hyaluronic acid salts with the water retention and humectant properties of larger variants. This is one of the newer types of hyaluronic acid.

Though they may not penetrate as deep as hyaluronic acid salts, they offer a balance that brands and formulators find valuable.

Choosing the Right Hyaluronic Acid for Your Routine

In essence, all forms of hyaluronic acid share the ability to hydrate the skin. The critical factor lies in their penetration levels and water retention capacities. Tailoring your skincare routine to specific hyaluronic acid types can address your unique concerns effectively.
