The Up & Up on Sodium Hyaluronate
You may mistake sodium hyaluronate for hyaluronic acid—and you're not alone in this. Although they're similar and related, sodium hyaluronate is much different from hyaluronic acid. First brought to light and commercially used in the late 70s and early 80s, sodium hyaluronate was originally meant for treating bone and joint disorders or conditions. As sodium hyaluronate is fast becoming a prominent ingredient in the skincare and beauty industry, here's all you need to know about its benefits and how it works in the modern market.
What is Sodium Hyaluronate?
Hyaluronic acid comes in two salt forms: potassium hyaluronate and sodium hyaluronate. As you may have guessed, sodium hyaluronate is the sodium salt of hyaluronic acid, and its uses range from joint pain injections and eye treatments to anti-wrinkle skin injections. When extracted from its parent molecule, sodium hyaluronate assumes an entirely different function and appearance. In terms of molecular weight, it's much lighter than hyaluronic acid, making it easier for it to penetrate the top layer of the skin and drastically improve the layers beneath.
More Skin Benefits of Sodium Hyaluronate
Some product ingredient lists may falsely state that sodium hyaluronate is hyaluronic acid; although not too common, knowing their key differences can make you a more informed shopper. Here are the major benefits of sodium hyaluronate to look out for:
- Moisturizing properties of sodium hyaluronate help attract moisture into the skin, thus reducing dryness, flakiness, and conditions like eczema. Thanks to its lower molecular weight, sodium hyaluronate is said to have a greater hydrating effect than hyaluronic acid and leaves the skin looking plumper and more glowing.
- Sodium hyaluronate has anti-inflammation properties that help reduce the inflammatory activity of cells and can reduce redness and burning sensations. This is particularly helpful in treating conditions like rosacea and also aids in healing wounds on the skin and accelerates the process.
- Anti-aging and barrier repair: Sodium hyaluronate is essential for replacing lost moisture due to aging and smooths out textures and fine lines or wrinkles. It also helps maintain a healthy moisture barrier by preventing trans-epidermal water loss.
