Sodium hyaluronate has gained immense popularity in the skincare and cosmetic industries due to its incredible ability to retain moisture and its versatility as a key ingredient in many products. Often found in moisturizers, serums, and anti-aging creams, sodium hyaluronate is a derivative of hyaluronic acid, a substance naturally present in the human body. However, despite their similarities, sodium hyaluronate and hyaluronic acid have distinct characteristics that make them suitable for different applications in skincare.
What is sodium hyaluronate, and why is it used in skin care?
Sodium hyaluronate is the sodium salt form of hyaluronic acid, and it is commonly used in skincare products for its superior hydrating properties. It can hold a thousand times its weight in water, making it a powerful moisturizer that helps to retain moisture in the skin, providing hydration and promoting a healthy, plump appearance. This makes it a popular choice for addressing dry skin and aging concerns.
In this article, we will explore what sodium hyaluronate is, how it works in skin care, its benefits, and why it has become such a sought-after ingredient in modern skincare formulations.

Sodium hyaluronate and hyaluronic acid are closely related, but there are distinct differences between the two. Both compounds are made up of the same substance—hyaluronic acid—but sodium hyaluronate is the sodium salt form, which allows it to penetrate deeper into the skin and be more stable in different formulations.
Molecular Size: Hyaluronic acid is a larger molecule, which means it has a harder time penetrating the skin's deeper layers. In contrast, sodium hyaluronate, being smaller in size, is more easily absorbed by the skin, allowing for deeper hydration and effectiveness.
Stability: Sodium hyaluronate is more stable in cosmetic formulations. It is less prone to degradation when exposed to air and light, which makes it ideal for long-lasting products.
Hydration: Both sodium hyaluronate and hyaluronic acid retain moisture, but sodium hyaluronate is often preferred in topical skincare because of its ability to hydrate skin at a deeper level and provide long-lasting moisture.
The two forms of hyaluronic acid work in slightly different ways, but both contribute to improving skin hydration, texture, and elasticity. Sodium hyaluronate is often preferred in skin care products because of its smaller molecular size, which allows for more effective and deeper absorption.
Sodium hyaluronate is widely used in skin care products due to its incredible hydrating and anti-aging properties. As a humectant, sodium hyaluronate attracts moisture from the environment into the skin, helping to keep the skin hydrated for longer periods. It also helps to enhance the skin’s barrier function, preventing water loss and improving overall skin health.
Some of the key benefits of sodium hyaluronate in skin care include:
Deep Hydration: Sodium hyaluronate can hold up to 1000 times its weight in water, making it an exceptional hydrating agent. It draws moisture into the skin, plumping and smoothing the appearance of dry or dehydrated skin.
Anti-Aging Effects: As we age, our skin loses moisture and elasticity, which can lead to wrinkles and fine lines. Sodium hyaluronate helps to improve skin elasticity by providing lasting hydration, reducing the appearance of wrinkles, and giving the skin a more youthful appearance.
Improved Skin Texture: By keeping the skin hydrated, sodium hyaluronate helps to create a smooth and even texture. It enhances the skin's natural barrier function, which can help improve the overall appearance of the skin and reduce rough patches.
Soothing Properties: Sodium hyaluronate has anti-inflammatory properties that can help calm irritated or sensitive skin, making it a great option for those with conditions like rosacea or eczema.
Because of these benefits, sodium hyaluronate is often used in serums, moisturizers, face masks, and eye creams to deliver instant hydration and long-term skin health.
In addition to its widespread use in skincare, sodium hyaluronate also has a range of medical applications, particularly in the fields of orthopedics and ophthalmology. Some of the notable medical benefits include:
Joint Health: Sodium hyaluronate is commonly used in injectable form to treat osteoarthritis. When injected into the joint, it helps to lubricate the area, reduce pain, and improve mobility by supplementing the body’s natural hyaluronic acid, which may decrease in quantity due to aging or injury.
Eye Health: Sodium hyaluronate is used in eye drops to treat dry eye syndrome. It provides moisture and relief to the eye surface, helping to alleviate symptoms like irritation and discomfort caused by dryness.
Wound Healing: Sodium hyaluronate is used in some wound care treatments because it promotes tissue regeneration and accelerates the healing process. It helps maintain moisture at the wound site and enhances the formation of new cells, reducing scarring.
Facial Aesthetic Treatments: Sodium hyaluronate is commonly used in dermal fillers to restore volume and smooth wrinkles. It is a popular choice for facial aesthetic treatments due to its biocompatibility and ability to retain moisture, offering a natural, plumping effect.
In medical applications, sodium hyaluronate serves as an effective agent for both therapeutic and cosmetic procedures, enhancing healing, lubrication, and tissue regeneration.
Sodium hyaluronate is available in various forms, each suited to different applications. Whether you’re looking for a topical treatment for your skin or a medical solution for joint pain, sodium hyaluronate is versatile enough to be used in many different ways. Some of the most common forms include:
Topical Serums and Creams: Sodium hyaluronate is commonly found in serums, moisturizers, and eye creams. Its lightweight texture allows it to penetrate deeper into the skin, delivering hydration and promoting elasticity.
Injections: For medical purposes, sodium hyaluronate is often injected into joints to treat osteoarthritis or used in dermal fillers for facial aesthetics.
Eye Drops: Sodium hyaluronate eye drops are used to treat dry eyes by providing long-lasting moisture and relief from irritation.
Oral Supplements: In some cases, sodium hyaluronate is available as an oral supplement, especially for joint health. These supplements may help improve joint lubrication and support the health of connective tissues.
Wound Care Products: Sodium hyaluronate is also available in gel or cream form for use in wound healing, helping to promote faster tissue regeneration and reduce scarring.
Each form of sodium hyaluronate has its own unique benefits depending on the specific needs of the user, whether it be hydration for skin or relief from joint pain.
Sodium hyaluronate is a powerful ingredient in skincare and medicine due to its exceptional ability to retain moisture, promote healing, and improve skin elasticity. Its use in topical skincare products helps to deeply hydrate and plump the skin, while its medical applications in joint care, eye health, and wound healing demonstrate its versatility.
In skincare, sodium hyaluronate stands out for its ability to improve texture, reduce fine lines, and soothe irritated skin. Whether applied topically or used in injectable or oral forms, sodium hyaluronate is a valuable ingredient in modern health and beauty treatments.
