Sodium Hyaluronate

Sodium Hyaluronate — the sodium salt of hyaluronic acid, a form that is more stable and typically has a smaller molecular size. This makes it a common ingredient choice that spreads easily and delivers humectant hydration into the skin.

Key points

• Sodium hyaluronate is the salt form of hyaluronic acid, often preferred for its stability in formulations.
• Its generally smaller molecular size allows it to distribute and penetrate more readily than large hyaluronic acid.
• Like hyaluronic acid, it acts as a humectant that binds water to hydrate the skin.
• It is frequently listed on ingredient labels as the actual form of hyaluronic acid used in a product.

Can sodium hyaluronate be used daily?

Sodium hyaluronate is a gentle humectant that is generally suitable for daily use in morning and evening routines.
