Sodium Hyaluronate Crosspolymer is a chemically cross-linked form of sodium hyaluronate that forms a hydrated network, providing enhanced moisture retention and longer-lasting surface hydration compared to standard hyaluronic acid. It is widely used in moisturizers, serums, and masks to plump and smooth the skin surface.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient stinging or irritation | Rare | Usually related to other formulation components rather than the polymer itself. |
| Contact dermatitis / allergic reaction | Very rare | Hypersensitivity to hyaluronic acid derivatives is uncommon but has been documented. |
| Temporary skin tightness or film sensation | Uncommon | Due to the film-forming hydrated network as it dries on the skin. |
