Allergy & Safety Information
Sodium Hyaluronate is considered safe for cosmetic use. No significant safety concerns have been identified at typical use concentrations. As with any cosmetic ingredient, discontinue use if irritation occurs.
This ingredient is considered low risk from an allergenicity perspective. Reactions are uncommon at typical cosmetic use concentrations. However, no ingredient is universally safe — if you notice redness, itching, or irritation after using a product containing this ingredient, discontinue use and monitor whether symptoms resolve.
About Humectant Ingredients
Humectants attract water molecules from the environment and from deeper skin layers, drawing moisture into the stratum corneum. They are among the safest cosmetic ingredients — molecules like glycerin, hyaluronic acid, and panthenol have extremely low sensitisation rates and are well-tolerated by almost all skin types.
Relevance for Sodium Hyaluronate: In very low humidity environments, humectants can draw moisture out of the skin rather than into it. This is particularly relevant for high-molecular-weight hyaluronic acid applied to dry skin without an occlusive layer to seal moisture in.
How to Identify Sodium Hyaluronate in Products
Cosmetic ingredients are listed by their INCI (International Nomenclature of Cosmetic Ingredients) name in descending order of concentration. To check whether a product contains Sodium Hyaluronate, scan the ingredient list for its INCI name exactly as it appears above. Ingredients present at 1% or less may appear in any order after the 1% threshold.
Product types to prioritise checking: Serum, Moisturizer, Eye cream. These product categories are the most common sources of Sodium Hyaluronate exposure based on formulation data.
