Origin and History
Sodium Hyaluronate is a derivative of Hyaluronic Acid, naturally occurring in the human body and found abundantly in connective tissues, skin, and eyes. Its hydrating properties were discovered through medical research focused on joint health and eye care, and it was later introduced into skincare for its remarkable ability to draw moisture into the skin. Over the years, it has become a staple in hydrating and anti-aging skincare products due to its moisture-retention benefits.
Physical Properties
Sodium Hyaluronate appears as a white, odorless powder that is highly soluble in water, forming a clear, viscous solution. It has a low molecular weight compared to Hyaluronic Acid, allowing it to penetrate deeper into the skin layers, which provides enhanced hydration.
Description
Sodium Hyaluronate is celebrated in skincare for its outstanding ability to attract and retain moisture, making it a popular choice for hydration-focused formulations. As a humectant, it draws water from the environment and deeper skin layers, helping to keep the skin soft, plump, and resilient.
Due to its smaller molecular size, Sodium Hyaluronate can penetrate the skin more easily than regular Hyaluronic Acid, allowing it to deliver hydration more effectively to deeper layers of the skin. This property makes it especially beneficial in targeting dryness and reducing the appearance of fine lines. Sodium Hyaluronate is commonly included in serums, moisturizers, and eye creams, delivering long-lasting hydration and a visibly smoother, more youthful appearance.
