Hyaluronic Acid (HA) is celebrated for its incredible hydrating capabilities, but not all HA is created equal. The efficacy of Hyaluronic Acid in skincare is significantly influenced by its molecular weight, which dictates its penetration ability and the specific benefits it offers. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing Hyaluronic Acid with precisely controlled molecular weights to meet diverse formulation needs.

Understanding hyaluronic acid molecular weight and skin penetration is key to unlocking its full potential. Generally, HA molecules are large polysaccharides. However, through advanced production techniques, HA can be processed into various sizes, each with unique properties:

  • High Molecular Weight Hyaluronic Acid (HMW HA): Molecules typically above 1,000 kDa (kilodaltons). These larger molecules are too big to penetrate deeply into the skin. Instead, they form a moisturizing film on the skin's surface, providing immediate hydration, smoothing, and a protective barrier against environmental aggressors. This is excellent for surface hydration and achieving that plump, dewy look, aligning with the goals of hyaluronic acid for skin hydration.
  • Medium Molecular Weight Hyaluronic Acid (MMW HA): Molecules ranging from 500 kDa to 1,000 kDa. These can penetrate into the upper layers of the epidermis, offering deeper hydration and potentially contributing to skin repair and elasticity. They provide a balance between surface hydration and deeper moisturization, enhancing the benefits of hyaluronic acid for anti-aging.
  • Low Molecular Weight Hyaluronic Acid (LMW HA): Molecules below 500 kDa, often in the range of 50-200 kDa. These smaller molecules can penetrate more effectively into the stratum corneum and even deeper layers of the epidermis. LMW HA is known for its ability to deeply hydrate, improve skin elasticity, and potentially stimulate collagen production, contributing to long-term anti-aging effects. This is a critical component when considering targeted anti-aging solutions.

The concentration and combination of different molecular weights are also vital for optimal results. Many high-performance skincare products utilize a blend of HA molecules to provide both immediate surface benefits and long-term deep hydration and repair. Understanding how hyaluronic acid works in cosmetics often means appreciating this multi-faceted approach.

NINGBO INNO PHARMCHEM CO.,LTD. employs advanced manufacturing processes, including controlled bio-fermentation of hyaluronic acid, to produce HA with specific, consistent molecular weight profiles. This precision ensures that our clients can formulate products that effectively target various skin concerns, from dryness to the visible signs of aging.

Whether you are seeking to boost surface hydration or achieve deeper rejuvenation, the molecular weight of Hyaluronic Acid is a critical factor. By selecting the appropriate HA grade, formulators can enhance product efficacy and deliver superior results, reinforcing the safety of topical hyaluronic acid when used correctly.
