Sodium Hyaluronate Crosspolymer

INCI: Sodium Hyaluronate Crosspolymer

Sodium hyaluronate crosspolymer is a cross-linked form of hyaluronic acid in which standard HA molecules are chemically bonded to create a mesh-like structure. This cross-linking gives it a remarkable water-binding capacity approximately five times greater than standard hyaluronic acid, forming a water-filled gel that delivers sustained, long-term hydration and a smooth film on the skin surface.

Is Sodium Hyaluronate Crosspolymer safe? Key considerations

Can Sodium Hyaluronate Crosspolymer cause irritation?

Low Risk

Sodium hyaluronate crosspolymer is a skin-identical ingredient that is well tolerated by all skin types. No EU CosIng Annex II or III restrictions apply. Research has shown a 27.8% reduction in transepidermal water loss, indicating barrier-supportive rather than barrier-disruptive properties.

Does Sodium Hyaluronate Crosspolymer increase sun sensitivity?

No Risk

Sodium hyaluronate crosspolymer does not increase photosensitivity. No sun protection precautions are required.

Is Sodium Hyaluronate Crosspolymer safe during pregnancy?

Safe

Sodium hyaluronate crosspolymer is a derivative of hyaluronic acid, a naturally occurring substance in human skin. It is considered safe for topical use during pregnancy with no known reproductive or developmental concerns.
