Things worth knowing about "Sodium hyaluronate"
Sodium hyaluronate is the sodium salt of hyaluronic acid, widely used in medicine and cosmetics. It retains moisture, lubricates joints, and supports skin elasticity.
What is Sodium Hyaluronate?
Sodium hyaluronate is the sodium salt of hyaluronic acid, a naturally occurring polysaccharide found throughout the human body. It belongs to the group of glycosaminoglycans and is a key component of connective tissue, synovial fluid (joint fluid), the vitreous humor of the eye, and the skin. Sodium hyaluronate has a remarkable capacity to bind water molecules many times its own weight, making it a vital humectant and structural molecule in the body.
Mechanism of Action
Sodium hyaluronate functions as a viscoelastic polymer that binds water and gives tissues a gel-like consistency. In joints, it acts as a lubricant and shock absorber, reducing friction between cartilage surfaces. In the skin, it provides volume, elasticity, and hydration. At the cellular level, sodium hyaluronate interacts with receptors such as CD44 and RHAMM, which are involved in cell migration, wound healing, and regulation of inflammation.
Medical Applications
Ophthalmology
In eye surgery, sodium hyaluronate is used as a viscoelastic agent during cataract operations to protect ocular tissue and maintain the anterior chamber of the eye. As eye drops (artificial tears), it effectively relieves symptoms of dry eye syndrome by forming a protective, lubricating film on the surface of the eye.
Orthopedics and Rheumatology
In cases of osteoarthritis (joint degeneration), sodium hyaluronate is administered as an intra-articular injection directly into the affected joint, most commonly the knee. This procedure, known as viscosupplementation, aims to restore the natural properties of synovial fluid, reduce pain, and improve joint mobility.
Dermatology and Aesthetic Medicine
As a dermal filler, sodium hyaluronate is used to smooth wrinkles, augment lip volume, and contour facial features. These fillers are biocompatible and are gradually broken down by the body over several months. Sodium hyaluronate is also a popular active ingredient in moisturizers, serums, and wound dressings.
Wound Healing
Sodium hyaluronate supports cell migration and proliferation and is therefore incorporated into wound gels and dressings to accelerate wound healing and minimize scar formation.
Dosage and Forms of Administration
Sodium hyaluronate is available in several formulations:
- Eye drops: 0.1–0.4% solution, applied several times daily
- Intra-articular injection: 10–25 mg per injection, administered one to five times at weekly intervals
- Dermal fillers: Concentration and degree of crosslinking vary depending on the area treated
- Oral supplements: Daily doses of 80–200 mg are being investigated in clinical studies
- Topical products: 0.1–2% in creams and serums
Side Effects and Safety
Sodium hyaluronate is generally well tolerated, as it is a substance naturally produced by the body. Possible side effects include:
- Local reactions after injections (redness, swelling, pain)
- Rarely: hypersensitivity reactions or granuloma formation with dermal fillers
- Eye drops: transient blurred vision
During pregnancy and breastfeeding, injectable formulations should only be used after consulting a healthcare professional.
Sodium Hyaluronate in the Diet
Small amounts of hyaluronic acid can be obtained through certain foods, such as bone broth, collagen-rich preparations, and soy-based products. However, the clinical relevance of dietary intake is limited compared to medical applications.
