Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycanfound in various connective, epithelial, and neural tissues.
Treating knee pain in patients with osteoarthritis who have not received relief from other treatments.
Hyaluronate sodium is a hyaluronic acid derivative. It works by increasing the effectiveness of the fluid within the knee joint to act as a lubricant and shock absorber.
The magic of this ingredient lies in its ability to retain moisture; it’s considered to have a greater capacity to hold moisture than any other natural or synthetic polymer. In fact, one gram of hyaluronic acid is able to hold up to six liters of water!
This is important with regard to aging because one of the hallmarks of youthful skin is its moisture content. As we age, our skin loses moisture, resulting in a loss of firmness and pliability.
Note: This does not mean that everyone’s skin becomes dry with age; it simply means that skin lacks the amount of moisture it had in its youth due to sun damage and/or other factors. Without question, you can still have oily skin in your 60s (perhaps just not as oily as it was in your 20s)!
Hyaluronic acid can improve your skin’s moisture content and at the same time strengthen skin’s barrier; that is, the outer layers of your skin. A healthy barrier looks and feels softer, smoother, and plumper—all hallmarks of younger-looking skin! But, with hyaluronic acid, that’s not all you get—there are many additional benefits beyond just a more youthful appearance.
We know that just about everything, from sun damage and acne to sensitive skin and rosacea, can lead to a damaged barrier, so repairing skin’s barrier with skin-identical ingredients, like hyaluronic acid (as detailed in this article), can go a long way toward fixing, or at least minimizing, those issues, which means it’s helpful for all skin types. Its lightweight texture isn’t an issue for oily skin, and it’s gentle enough that it isn’t a problem for sensitive skin.
Even better: Hyaluronic acid also provides antioxidant defense against free-radical damage, and reduces inflammation. Now that’s what we call a multitasking anti-aging ingredient!
Adverse effects are relatively rare when used to treat the joints.
When used in ophthalmological procedures, sodium hyaluronate may cause postoperative inflammation, corneal edema or decompensation, and short-term increases in intraocular pressure.
