Hyaluronic Acid - HMW (High Molecular Weight)

Hyaluronic Acid – HMW (High Molecular Weight) is a premium, water-soluble cosmetic ingredient valued for its exceptional moisture-binding and skin-hydrating properties. Supplied as Sodium Hyaluronate, this high molecular weight grade ranges from approximately 1.6–2.0 million Daltons (1.6M–2.0M Da).

Hyaluronic acid is a polysaccharide naturally present in the human body and is well known for its ability to attract and retain moisture. In cosmetic formulations, Sodium Hyaluronate acts as a powerful humectant, helping increase skin hydration and leaving the skin feeling smoother, softer and more supple.

Why High Molecular Weight Hyaluronic Acid?

Unlike lower molecular weight grades, High Molecular Weight (HMW) Hyaluronic Acid primarily works at the surface of the skin, where it forms a lightweight, moisture-retaining film.

This surface hydration helps reduce moisture loss and support the skin's moisture barrier, providing an immediate smoothing and plumping effect. It is particularly well suited for formulations designed to improve the appearance and feel of dry, dehydrated or mature skin.

Formulation Information

Recommended Usage Rate: 0.1–2%

Hyaluronic Acid HMW is water soluble and should be incorporated into the water phase of a formulation. As with other high molecular weight polymers, proper dispersion and sufficient hydration time are recommended to minimize clumping and achieve uniform incorporation.
