What is Sodium Hyaluronate?
In the quest for radiant and youthful skin, one ingredient has taken the spotlight – Sodium Hyaluronate. This powerhouse compound, derived from hyaluronic acid, plays a pivotal role in skincare.
Sodium hyaluronate is the sodium salt form of hyaluronic acid, a naturally occurring substance in the human body. It is a key component of connective tissues, skin, and the fluid that lubricates joints. Sodium hyaluronate is widely used in skincare and medical applications for its remarkable ability to retain water, making it a powerful hydrating and moisturizing agent.
Is sodium hyaluronate the same thing as hyaluronic acid?
They are related compounds but are not exactly the same thing.
- Hyaluronic Acid:
Molecule Structure: Hyaluronic acid is a large, naturally occurring molecule composed of repeating units of glucuronic acid and N-acetylglucosamine.
In the Body: It is found in various tissues, including the skin, connective tissues, and the synovial fluid of joints.
Function: Hyaluronic acid has an incredible capacity to retain water, providing hydration and lubrication. It also plays a role in supporting the structure and elasticity of the skin.
- Sodium Hyaluronate:
Formation: Sodium salt form of hyaluronic acid.
Smaller Molecule: It has a smaller molecular size compared to hyaluronic acid.
Skin Penetration: Due to its smaller size, sodium hyaluronate can penetrate the skin more easily, making it a common ingredient in skincare products.
In skincare formulations and medical applications, hyaluronic acid is often converted into its sodium salt form, sodium hyaluronate, for enhanced stability and skin penetration.
Functions of Sodium Hyaluronate
1. Hydration and Moisture Retention:
Sodium hyaluronate is renowned for its exceptional water-holding capacity. It can hold up to 1,000 times its weight in water, contributing to intense hydration and moisture retention in the skin.
2. Skincare Applications:
Commonly found in skincare products such as serums, creams, and masks, it helps improve skin texture, reduce the appearance of fine lines and wrinkles, and enhance overall hydration.
3. Collagen Support:
It plays a role in supporting collagen, a structural protein crucial for maintaining skin elasticity and firmness. It promotes a plump and youthful appearance.
4. Anti-Aging Benefits:
By providing optimal hydration and supporting collagen synthesis, it contributes to anti-aging efforts, helping to minimize the visible signs of aging.
5. Joint Lubrication:
In the medical field, sodium hyaluronate is used in joint injections to provide lubrication and reduce friction in conditions like osteoarthritis.
6. Wound Healing:
Its presence in the skin aids in wound healing and tissue repair. Sometimes used in medical settings to promote healing after certain surgeries or procedures.
Production Process of Sodium Hyaluronate
The process begins with the extraction of hyaluronic acid from a natural source, often through a process known as biofermentation. This sustainable method ensures the purity and quality of the hyaluronic acid.
To refine the extracted hyaluronic acid, purification steps are employed. This process involves removing impurities, ensuring good quality.
C. Sodium Binding:
It is created by binding hyaluronic acid with sodium. This modification enhances its stability and makes it more compatible with the skin.
D. Molecular Weight Adjustment:
Sodium hyaluronate comes in various molecular weights, each serving a specific purpose in skincare. High molecular weight is ideal for surface hydration, while low molecular weight penetrates deeper for a more profound, long-lasting effect.
