Polydextrose is a water-soluble glucose polymer used in skincare as a humectant and film-forming conditioning agent that helps hydrate and smooth the skin surface. It is also valued for its prebiotic potential to support the skin microbiome.

| Mild transient skin irritation | Rare | Occasional reports of slight redness or stinging, typically in sensitive skin or at high concentrations. |
| Contact allergic reaction | Very rare | Allergic sensitization is uncommon; polydextrose is generally considered low-risk and well tolerated. |
