Sodium hyaluronate is the salt form of hyaluronic acid, a naturally occurring substance found in your skin that acts like a moisture magnet. In skincare products, it absorbs water from the environment and binds it to your skin, helping to hydrate and plump the skin's surface.
Benefits
- Delivers intense hydration to the skin
- Helps reduce the appearance of fine lines by improving skin moisture
- Supports skin barrier function
- Suitable for all skin types, including sensitive and oily skin
Potential concerns
- In very dry climates with low humidity, it may draw moisture from deeper skin layers if not sealed with an occlusive product
- Rare allergic reactions are possible but extremely uncommon
Science: While the provided research focuses on intra-articular injections for joint health (showing good safety and efficacy), hyaluronic acid and its salt form are well-established in dermatology for topical hydration. The molecule's safety profile is well-documented across decades of use in medical and cosmetic applications, with severe adverse reactions being extremely rare.
