For cosmetic formulators, selecting the right ingredients is the bedrock of creating effective and appealing products. Hyaluronic Acid (HA), also known as Sodium Hyaluronate, is a prime example of an ingredient whose efficacy is closely tied to its properties, particularly its molecular weight. Understanding these distinctions is vital for optimizing formulation outcomes. NINGBO INNO PHARMCHEM CO.,LTD., a leading supplier in China, offers a comprehensive range of Hyaluronic Acid to meet diverse formulation needs. If you are looking to buy Hyaluronic Acid, this guide will assist you.

The molecular weight of Hyaluronic Acid significantly influences its behavior and benefits when applied to the skin. Generally, HA is categorized by its molecular size, ranging from ultra-low to very high molecular weights. Each range offers unique advantages for specific cosmetic applications.

Ultra-Low to Low Molecular Weight Hyaluronic Acid (typically < 100,000 Da): These smaller molecules are capable of penetrating the stratum corneum, the outermost layer of the epidermis. This allows them to reach deeper skin layers, providing hydration at a cellular level, promoting skin regeneration, and aiding in the repair of the skin barrier. They are particularly effective for products targeting dehydration, fine lines, and improving skin elasticity from within. When you buy Hyaluronic Acid for deep hydration, opt for these lower molecular weight variants.

Medium Molecular Weight Hyaluronic Acid (typically 100,000 Da - 1,000,000 Da): This range offers a balance of benefits. Medium molecular weight HA can hydrate the surface layers of the skin and also has some ability to penetrate the epidermis. It contributes to improved skin texture, hydration, and acts as an effective moisturizing agent. These grades are versatile and suitable for a wide array of skincare products, providing a substantial hydration boost.

High Molecular Weight Hyaluronic Acid (typically > 1,000,000 Da): Due to their large size, these molecules remain on the skin's surface, forming a continuous, hydrating film. This film acts as a protective barrier, reducing transepidermal water loss (TEWL) and safeguarding the skin from environmental aggressors. HMW HA provides immediate surface hydration, plumping the skin and giving it a smooth, dewy finish. It's ideal for products focused on barrier function and surface-level moisture lock-in.
