Sodium Hyaluronate vs. Hyaluronic Acid: Unraveling the Skincare Conundrum (Sodium Hyluronate is used in all our skincare products)
Hyaluronic acid (HA) and its derivative, sodium hyaluronate (SH), are power players in the realm of skincare. Both are celebrated for their exceptional hydrating properties and their ability to plump and rejuvenate the skin. However, understanding the nuances between these two forms is crucial to make informed decisions about which one might be better suited for your skincare needs.
Hyaluronic Acid: A Brief Overview: Hyaluronic acid is a naturally occurring polysaccharide found in the human body. It plays a vital role in maintaining hydration, collagen production, and elasticity in the skin. In its pure form, HA has a higher molecular weight, making it less penetrative but highly effective in locking in moisture on the skin's surface.
Sodium Hyaluronate: The Salt of Hyaluronic Acid: Sodium hyaluronate, derived from hyaluronic acid, is the salt form of HA. It is created by modifying HA through a process called hydrolysis to reduce its molecular size. The result is a lower molecular weight, which allows for better skin penetration and absorption.
Comparative Advantages:
Absorption and Penetration: Sodium hyaluronate, with its lower molecular weight, can penetrate the skin more effectively than HA. Its smaller size allows it to reach deeper layers of the skin, delivering hydration where it's needed most.
Stability and Shelf Life: Sodium hyaluronate is more stable and has a longer shelf life compared to hyaluronic acid. Its stability makes it a preferred choice for formulating skincare products, ensuring the product remains effective over time.
Reduced Potential for Irritation: Sodium hyaluronate is generally considered gentler and less likely to cause skin irritation. In contrast, pure hyaluronic acid, especially in its high molecular weight form, may sometimes cause irritation, especially for those with sensitive skin.
Compatibility in Formulations: Sodium hyaluronate is highly compatible with other skincare ingredients, allowing its integration into a variety of skincare products. This compatibility enhances its efficacy and makes it a versatile choice for skincare formulations.
Conclusion: In the skincare world, both sodium hyaluronate and hyaluronic acid play essential roles in providing hydration and promoting skin health. The choice between the two depends on factors such as the desired depth of penetration, skin sensitivity, and product stability. Sodium hyaluronate, with its superior absorption and reduced potential for irritation, is often the favoured choice in modern skincare formulations. However, both forms offer significant benefits, ensuring your skin remains hydrated, plump, and youthful.
