For those who aren’t chemists, reading the ingredient list on a skincare product can feel overwhelming. On top of trying to remember which ingredients to avoid or seek out, brands often use different names for essentially the same ingredient. Take hyaluronic acid, for example—a popular skin hydrator you’re likely familiar with. But how much do you know about sodium hyaluronate? You might be surprised to learn that the hyaluronic acid serum you've been using may actually contain sodium hyaluronate. While there are some differences, the two ingredients are quite similar and serve the same purpose in skincare.
Sodium Hyaluronate
Type of ingredient: Humectant.
Key benefits: Hydrates the skin, reduces the appearance of wrinkles, replenishes moisture, and supports skin structure and volume.
How often can you use it: Safe to use in concentrations up to 2% twice a day, both in the morning and at night.
Works well with: Moisturizers.
Avoid using with: Sodium hyaluronate is generally compatible with most skincare ingredients.

What Is Sodium Hyaluronate?
Sodium hyaluronate is a water-soluble salt derived from hyaluronic acid, which is naturally present in the body, according to dermatologists. Similar to hyaluronic acid, sodium hyaluronate is a powerful hydrator, but it can penetrate deeper into the skin and remains more stable in skincare formulations. Sodium hyaluronate as a fiber-like or cream-like powder commonly found in moisturizers and serums. As a humectant, it draws moisture from both the environment and deeper skin layers into the epidermis, serving as a "water reservoir" that regulates moisture levels in the skin.
Benefits of Sodium Hyaluronate for Skin
Sodium hyaluronate provides key hydration benefits that address various skin concerns linked to dryness:
Fights dryness: As a humectant, it draws water from the air, keeping skin hydrated and free of flakes.
Repairs moisture barrier: Essential for maintaining a healthy barrier, it helps prevent transepidermal water loss (TEWL), reducing the risk of inflammation.
Reduces signs of aging: By restoring moisture and replenishing lost hyaluronic acid, it can smooth the skin, minimizing fine lines and wrinkles.
Improves acne-prone skin: Sodium hyaluronate can balance the skin’s moisture if it’s been over-dried by harsh treatments, and it’s non-comedogenic, so it won’t clog pores.
Plumps the skin: Provides structure and volume, giving the skin a temporary but instant plump look.
Reduces wrinkles: By plumping the skin, it helps smooth out fine lines and wrinkles.
Eases inflammation: A 2013 study found that sodium hyaluronate in creams helped calm inflammatory skin conditions.
Leaves a lightweight glow: It delivers hydration without leaving a heavy or greasy residue, offering a dewy finish.
Helps eczema: Safe for sensitive skin, it’s especially beneficial for extremely dry or eczema-prone skin.
Restores post-procedure: We recommend sodium hyaluronate for post-procedure hydration, such as after laser treatments or microneedling, when skin is more vulnerable.
Who Should Use Sodium Hyaluronate
Sodium hyaluronate is beneficial for all ages and skin types but is particularly effective for those with dry or dehydrated skin.
Sodium Hyaluronate vs. Hyaluronic Acid
While the terms are often used interchangeably, sodium hyaluronate and hyaluronic acid are slightly different. Sodium hyaluronate, being the salt form of hyaluronic acid, is more stable and has a smaller molecular size, allowing it to penetrate deeper into the skin. Though hyaluronic acid primarily hydrates the skin’s surface, sodium hyaluronate absorbs more efficiently, though both serve the same purpose of hydration.
Forms of Sodium Hyaluronate for Skincare
You can find sodium hyaluronate in various skincare products like face washes, serums, lotions, and gels. Face washes with sodium hyaluronate cleanse the skin without stripping moisture. Serums, applied before a night cream or moisturizer, enhance hydration and complement other products. Lotions and gels improve the skin’s moisture barrier, offering a protective layer.
Side Effects of Sodium Hyaluronate
Sodium hyaluronate has no known side effects, but we recommend spot testing new products before full application. Also note that in very dry environments, sodium hyaluronate may not have enough moisture in the air to draw into the skin, which could make it less effective.
How to Use It
For best results, apply sodium hyaluronate serums or moisturizers once or twice daily on damp skin after washing your face or showering. We suggest following up with a heavier emollient to lock in moisture, particularly during the winter or if your skin is dry. This layering technique enhances the hydrating effects of sodium hyaluronate.
