Xanthan gum is a polysaccharide produced by bacterial fermentation, used in skincare as a thickening, gelling, and emulsion-stabilizing agent. It improves texture and suspends particles in formulations rather than providing a direct skin treatment effect.
| Reported effect | How often | Notes |

| Skin irritation | Rare | Mild irritation possible, typically in sensitive individuals or at high concentrations. |
