Xylose is a naturally occurring monosaccharide (pentose sugar) used in skincare primarily as a humectant and skin-conditioning agent, and as a component of certain anti-glycation and barrier-supporting formulations. It helps attract and retain moisture and may contribute to maintaining skin smoothness.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient stinging or irritation | Rare | Generally well tolerated; occasional irritation on sensitive or compromised skin. |
| Contact dermatitis / allergic reaction | Very rare | Isolated sensitivity reactions; uncommon for simple sugars. |
| Redness or erythema | Very rare | Typically associated with overall formulation rather than xylose itself. |
