Sodium hyluronate is the main ingredient in Restylane, an injectable filler used to treat loss of facial volume and wrinkles. It has other medical applications as well. Doctors sometimes use injections of sodium hyaluronate to treat knee pain due to arthritis. In this setting, it helps to lubricate the joint and reduce pain and inflammation. It also has various applications in the field of ophthalmology.
Hyaluronic acid doesn’t easily penetrate the skin when it’s applied topically, so it is most successful when injected into the dermis of the skin through fillers like Restylane. This is due to its large size. Sodium hyaluronate is smaller than hyaluronic acid and is able to move more freely into the deeper layers of the skin.
This is an advantage since sodium hyaluronate is a powerful humectant that attracts and holds on to water, making it the ultimate skin moisturizer. This helps to hydrate skin and keep it moist. Because it attracts and binds to water, it causes slight swelling. This swelling helps to reduce the appearance of fine lines and wrinkles and gives skin a more youthful appearance. In addition, the subtle swelling increases volume, which makes skin look younger.
