Hyaluronic Acid (HA), or Sodium Hyaluronate, is a cornerstone ingredient in many advanced formulations, particularly in cosmetics and pharmaceuticals. At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the efficacy of HA is closely tied to its molecular weight. This guide aims to demystify the different grades and their specific benefits, helping formulators and consumers make informed choices.

The term sodium hyaluronate molecular weight benefits refers to how the size of the HA molecule affects its performance. Generally, HA is categorized into three main types: high molecular weight (HMW-HA), medium molecular weight (MMW-HA), and low molecular weight (LMW-HA). Each plays a distinct role in skincare and other applications.

High molecular weight Hyaluronic Acid, typically ranging from 1.5 to 3 million Daltons, acts primarily on the skin's surface. Its large size creates a film that locks in moisture, providing immediate hydration and a smooth feel. It's excellent for surface hydration, protecting the skin barrier, and giving the skin a plump appearance. This is often the ingredient of choice for everyday moisturizers and protective creams.

Medium molecular weight Hyaluronic Acid, usually between 200,000 and 1 million Daltons, offers a balance of surface hydration and deeper penetration. It can help support the skin's natural barrier function and contribute to overall skin health by aiding in cell regeneration and reducing inflammation. This makes it suitable for products aimed at improving skin texture and resilience.

Low molecular weight Hyaluronic Acid, often below 200,000 Daltons (and sometimes as low as 5-10 kDa for ultra-low molecular weight), has smaller molecules that can penetrate deeper into the epidermis. This allows for more profound hydration and can stimulate collagen production, offering significant anti-aging benefits and promoting skin repair. When seeking deeper hydration and anti-wrinkle effects, LMW-HA is the preferred choice. For those looking for effective hyaluronic acid for skin care formulations, understanding these distinctions is crucial.

For manufacturers, selecting the right molecular weight is key to achieving desired product outcomes. Whether you need the surface-level hydration of HMW-HA or the deep-penetrating power of LMW-HA, a reliable hyaluronic acid powder supplier like NINGBO INNO PHARMCHEM CO.,LTD. can provide the optimal grade. Our commitment to quality ensures you receive pure, high-performance Hyaluronic Acid for all your formulation needs, whether for cosmetics, food, or eye drops.
