At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the efficacy of a cosmetic or health ingredient often lies in the specifics. Hyaluronic Acid (HA) powder is a prime example, with its effectiveness significantly influenced by its molecular weight and grade. For professionals and consumers alike, grasping these distinctions is crucial for selecting the right HA for optimal results. This guide aims to demystify these aspects of Hyaluronic Acid.

Hyaluronic Acid is a naturally occurring polysaccharide that is synthesized using biotechnology, typically through microbial fermentation. This process allows for the control of its molecular weight, which fundamentally dictates its properties and applications. We offer various grades, including cosmetic grade, food grade, and even injection grade, each tailored for specific uses.

The term 'molecular weight' for Hyaluronic Acid refers to the size of the molecule, usually measured in Daltons (Da) or kilodaltons (kDa). Different molecular weights interact with the skin and body in distinct ways, leading to a diverse range of benefits. Understanding these differences is key, especially when looking to buy hyaluronic acid powder for precise formulations.

Low molecular weight Hyaluronic Acid (typically below 100 kDa) has smaller molecules that can penetrate deeper into the epidermis. This characteristic makes it excellent for providing hydration from within, helping to plump the skin and potentially reduce the appearance of fine lines more effectively at deeper levels. Products featuring these smaller molecules are often marketed for their intensive, long-lasting hydration effects.

Medium molecular weight Hyaluronic Acid (ranging from 100 kDa to 1,600 kDa) offers a balance. These molecules can hydrate the skin's surface layers and also provide a degree of deeper penetration. They are commonly used in a wide array of skincare products, including moisturizers and serums, for overall skin hydration and improvement of texture.

High molecular weight Hyaluronic Acid (above 1,600 kDa) has the largest molecules. Due to their size, they primarily remain on the skin's surface, forming a protective, hydrating film. This film effectively locks in moisture, prevents transepidermal water loss (TEWL), and provides a smooth, supple feel to the skin. This type is excellent for immediate surface hydration and protection, and you'll often find it listed as a key ingredient in hyaluronic acid serum for skin.

When selecting Hyaluronic Acid, consider the grade as well. Hyaluronic acid cosmetic grade is specifically purified for use in beauty products, ensuring safety and effectiveness for topical application. Food grade HA is suitable for consumption, often found in supplements or functional foods. Injection grade is highly purified and sterilized for medical and cosmetic injectable procedures.
