What Is Low Molecular Weight Hyaluronic Acid / Sodium Hyaluronate?

Normally low molecular weight hyaluronic acid / sodium hyaluronate means sodium hayluronate with molecular weight ≤1,000K Da. The corresponding intrinsic viscosity is no more than 1.8 m3/kg.
For medical grade & injection grade sodium hyaluronate, we always measure intrinsic viscosity (m3/kg) instead of molecular weight (Dalton).

Low Molecular Weight Injection Grade Hyaluronic Acid / Sodium Hyaluronate: HA-EP1.8

Low Molecular Weight Medical Grade Hyaluronic Acid / Sodium Hyaluronate: HA-P-0.5

Low Molecular Weight Cosmetics Grade Hyaluronic Acid / Sodium Hyaluronate: HAC-L

Low Molecular Weight Food Grade Hyaluronic Acid / Sodium Hyaluronate: HAF-L
