Sodium Hyaluronate
Humectant that draws moisture into skin (hyaluronic acid salt).
What does Sodium Hyaluronate do for skin?
Sodium Hyaluronate is a powerful humectant, capable of attracting and binding large amounts of water (up to 1,000 times its weight) to the skin's surface. It forms a permeable, viscoelastic film on the stratum corneum, which helps to prevent trans-epidermal water loss (TEWL) and maintain optimal skin moisture levels. This enhanced surface hydration plumps the skin, reducing the appearance of fine lines and wrinkles, and improving skin elasticity and smoothness.
Typical concentration: 0.1-2.0% (most formulas use 0.1-1.0%)
Is Sodium Hyaluronate safe?
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Sodium Hyaluronate as safe for use in cosmetic formulations. It is widely regarded as non-irritating and non-sensitizing, with a very low potential for adverse skin reactions.

Can I mix Sodium Hyaluronate with other ingredients?
General guidance
Hyaluronic acid works best on damp skin. Apply right after cleansing while your face is still moist for maximum hydration.
HA draws water in, ceramides lock it in. Apply HA on damp skin first, then ceramide moisturizer to seal.
Excellent pair! Hyaluronic acid hydrates while niacinamide strengthens the skin barrier. Use together for plump, healthy skin.
Hyaluronic acid before retinoid helps buffer irritation and keeps skin hydrated. A great way to ease into retinoids.
Centella + hyaluronic acid provides deep hydration with calming benefits. Great for sensitive or irritated skin.
Both are hydration powerhouses. Layer hyaluronic acid first (thinner), then snail mucin (thicker) for max hydration.
Growth Factors
Hyaluronic acid on damp skin followed by growth factors ensures hydration and maximizes EGF/PDRN absorption.
Fermented Ingredients
Fermented first essences prep the skin for better hyaluronic acid absorption. Apply fermented product first.
Peptides
Hyaluronic acid + peptides is a hydrating anti-aging duo. Apply HA first (thinner), then peptide serum.
